But among all the stretching devices to be found on the penis enlargement market, only one stands out from the crowd. SizeGenetics is the original stretching device to hit the market a few years back and spark a trend that still goes on strong.

So you have decided to make the big step and actually join the hip penis enlargement community. No more denial, no more depression. Sure, the road happiness looks long and lonely from where you stand right now, but even a journey of a thousand miles starts with a single step.

And that first step was your decision to do something about the inadequate size of your penis. The second step is to find out which penis enlargement method is best suited for you. Of course, the final choice depends on your aesthetic preferences, readiness to perform complicated tasks and free time.

By exerting constant traction on your penis session after session, SizeGenetics is one of the fastest penis enlargement solutions available on the market.

You may wonder at this point whether we would also recommend pumps. Truth is we think pumps are far too unreliable and dangerous to be used. Pumps have not been endorsed by doctors as a valid penis enlargement method and should be used only by people suffering from diabetes or heart conditions in order to obtain erections.

If you have less free time and work in an office, then you may wish to try the PenisHealth system of penis enlargement exercises. This perfectly natural penis enlargement solution features a series of exercises that act in the same was as the traction device. The cells that make up the penis tissues are forced to expand and multiply, thus increasing both length and girth.

The exercises can be performed in the morning before going to work, or in the evening. One of the advantages offered by this solution is that you have absolute control of your penis enlargement experience at all times. The risk of accident is practically non-existent for any person who performs the exercises correctly.

But if you are not happy with either of the two methods outlined above, we are happy to recommend you the ProSolution Pills. These herbal penis pills can help you increase the size of your penis in a natural way with a minimum of fuss. They are easy to conceal and can be taken any time and any place.

The ingredients used in these pills help boost the flow of blood to the penis, pump up the production of testosterone and raise your energy levels, thus giving a kick start to your entire reproduction system. You don抰 need any risky surgery to enlarge your penis because better solutions are available. Why risk impotence, scars, loss of feeling and botched recoveries when penis enlargement can be so much simpler.

And we know that many men are wondering whether natural penis enlargement is possible and about the negative opinions voiced by the professional medical community. Frankly, the answer to such doubts and question is rather simple. Natural penis enlargement is just like natural medicine.

There are few trademarked substances around, which means that corporations cannot squeeze the patients dry and make huge piles of cash. Furthermore, doctors know that they抎 sooner see pigs fly than obtain money for studies into the effectiveness of natural penis enlargement methods.

Unless they can earn money by selling over-priced products from large pharmaceutical companies, the majority of doctors will not give the smaller, and often more effective treatments the time of day.

The Male Enhancement Market Today

The issue of male enhancement has now come out in the open and men are no longer ashamed to talk about it. There are safe ways of improving the size and making it larger and broader.

This is the 30th century and not just the 21st century. Many taboos of yesteryears have simply been washed away. With lots happening in technology especially in the medical field, people are able to enjoy the lifestyle that even their parents couldn抰. Earlier the market for penis enlargement was a very niche market and it operated by simply word of mouth. No longer is the case, you can seek advice from your doctors and there are many products and devices that can help the men lead a fuller and bigger life.

Over the years, the range of penis enlargement products has undergone a massive change. Earlier the penis enlargement devices consisted of only dull pumps, weights and pills. But now there are many other devices available for the enlargement of the penis. Many men are quite comfortable with the pills and the creams that are available. There are many traction devices available in the market that helps to enlarge the penis. Sure they are effective over a few weeks, but the wait is worth it.

Surgery is a controversial and an expensive proposition. Surgery for penile enlargement can cost upward of several thousand dollars. The potential fall outs are impotency, scarring and loss of sensation. Most men don抰 feel that it抯 really worth an option. Another significant issue is the fact that surgical procedures like the injection of fat have to be performed again and again since fat is absorbed back by the body, while injected silicone tends to migrate to other parts of the body. These factors combined have convinced men to look for cheaper and safer penis enlargement opportunities.

Men like to please their partners. They want to brag with their buddies about who has the biggest of them all. At the end of the day, they want to see the respect in the eyes of their lovers and colleagues. Penis enlargement helps them to achieve it. Men and women are looking at new ways to please their partners and look great in bed and perform well. They also want to attract more lovers and a big penis comes really handy, whichever way you use it.

The issue of penis enlargement has now come out in the open and men are no longer ashamed to talk about it. There are safe ways of improving the size and making it larger and broader. It抯 important to talk to a doctor before you use any of the devices.

The Myths of Penis Enlargement

Throughout the ages mankind has always been ready to make up for any lack of knowledge with a combination of intuition, deduction, observation and outright invention that is usually called myth. Myths are stories that are based to a certain degree on what men understood from the facts before them. Their purpose is to fill a gap either in knowledge or in morals.

A good example of a widespread myth that has no real basis and is meant to enforce a certain type of behavior is the old saying that masturbation makes men go blind. In fact a Swiss physician Samuel-Auguste Tissot said in 1760 that his studies proved that masturbation causes a perceptible reduction of strength, of memory and even of reason, blurred vision, all the nervous disorders, weakening of the sex organs disturbance of the appetite, headaches and a great number of other disorders. It goes without saying that most men living today know better than to believe that.

But grown men themselves are not spared the fear that myths are supposed to put into their souls. Another widespread myth claims that lack of sex over a longer period of time would certainly cause the penis or testicles to shrink. However, neither penis nor testicles size is in no way linked to the frequency of sex sessions or anything else of this kind.

Another all-time favorite is the series of myths linking penis size to that of another part of the body, usually the hands or feet. Again, there is no scientific evidence that penis size is related to that of any part of the body. Actually, studies conducted by experts found a weak correlation at most between the size of the penis and the size of a man feet. This means that the rule is good for, probably, one man in a hundred.

Less known myths also have their fans. Some men think that drinking water can help enlarge the penis, which is not true. While other muscles in the body can grow in size with the help of extra oxygen and water delivered by supplements or pills, this is not the case with the penis. The sponge-like tissues called Corpora Cavernosa are not designed to hold blood or any other liquid permanently, but only as long as sexual stimulation occurs.

While penis enlargement exercises share some features with the regular body building techniques, adding water to gain size is not among them. Penis exercises work by forcing the cells that make up the penis tissues to grown in number, using the body own mechanism of adapting to external pressure. The pace of the enlargement process can be increased with the help of penis enlargement pills that boost the flow of blood to the genital area and make sure production of testosterone by the body is at the right level.

The bottom line is, of course, that nobody should put any stock in myths. Most of them distort facts to achieve a certain end and should not be trusted. If you are not certain about the effect that some thing or other has on your penis size or sex life, then it better to ask a professional, preferably a doctor. This way you抣l find that many myths regarding the penis are just that: myths.

The Importance of Penis Hygiene

Hygiene is a cornerstone of modern civilization. We all know that people living in the period of time between the end of the Roman Empire and the beginning of the modern age were not particularly concerned with washing. Some saw washing as an unnecessary luxury, others saw it as the first step toward sinning by indulging the pleasures of flesh. Some doctors even claimed that bathing was harmful to the body or the mind.

Time has passed and mankind entered a new age. Nowadays many people wash every day and don抰 seem to suffer any of the side effects predicted by the doctors of less scientifically advanced times. Still, we can抰 really say that everybody on earth is fully aware and practicing the strictest personal hygiene. Of course, social pressure takes care of most problems, since men and women would feel too embarrassed if they were found wanting on personal hygiene.

However, while many people pay little attention to it, intimate hygiene is just as important as overall hygiene. The sex organs are more sensitive than other parts of the body and frequently engaged in intimate contact, which is why they should be as clean as possible, if not cleaner. Think about it. The last thing you want when you take a lady to bed is to discover that she抯 not a hygiene fan. It抯 a major turnoff and it works the same way for both partners.

To clean the penis start at the tip. Pull the foreskin back as far as it would go in order to expose the entire glans. Wash both the glans and the inside of the foreskin thoroughly, but gently. This is not supposed to cause pain, so be gentle with one of the most sensitive parts of your body. At the same time make sure that the glans is perfectly clean. The space between the glans and the foreskin is where the white substance known as smegma is formed.

Smegma is a mixture of dead epithelial cells shed by tissues, skin oils, moisture and bacteria. Since bacteria tend to thrive in any small place that has plenty of moisture, be sure to wash away all smegma from under the foreskin. Letting bacteria and dead tissue cells accumulate is a sure way of getting every woman抯 nightmare: a smelly penis.

This could easily destroy a relationship, since no woman would accept to live with a man who doesn抰 know or care to keep himself clean. Going down on a man whose penis smells is simply out of the question. Intimate hygiene is also important for penis enlargement. Using an enlargement device such as a traction device or a pump on an unclean penis will simply spread bacteria all over the penis.

Accumulated dirt, sweat and bacteria will certainly cause infections at one point or another in the future. Men who engage in penis enlargement exercises are also exposed to infections if they fail to maintain a high standard of intimate hygiene. That why warming up and down using hot water in the shower is recommended as a good way of preparing for a penis enlargement session and as a chance to clean the penis.

Circumcised men have to be even more careful about their intimate hygiene because they lack the foreskin that protects the sensitive glans from sweat, dust and all manner of substances that should not come into contact with the penis. Some men choose circumcision precisely because they think that losing the foreskin helps keep the penis clean.

However, there is an ongoing debate among experts about the hazards and benefits of circumcision. Many doctors say that removing the protective foreskin is less hygienic and exposes the glans to various bacteria that cause infections of the urinary tract. At the same time, other doctors maintain that the foreskin traps smegma and dirt and so, uncircumcised men are not spared the danger of infections.

Regardless of how you feel about circumcision, one thing is perfectly clear: hygiene, and especially intimate hygiene, is of the utmost importance to you. It keeps infections away from this sensitive area and makes sure that your sexual relationships will not suffer.

Penis Enlargement Strategies.

A look at the some of the available options for penis enlargement
Article: Penis enlargement, does it really work? What are the best ways to achieve penis enlargement? Is penis size really that important? How long does penis enlargement treatment take to be effective?

The following should NOT be regarded as medical advice or suggestions for treatment. Should you consider that you are suffering from a sexually related problems (impotency, erectile dysfunction or premature ejaculation) professional medical advice should be sought.

Is penis enlargement a real possibility?
The answer to this appears to be a resounding YES! With a little carefully applied research, you can find literally thousands of testimonials from satisfied men and their partners who have increased their penis size using the different methods explored below

This article considers four ways that are frequently used to gain extra length and girth, and for the sake of the squeamish, we’ll leave the discussion about surgery until last.

Pump It Up
Swallow and Rub
Lets Exercise
Under the Knife

Choosing the right option for you is dependent on what it is you wish to achieve, the amount of hard work you are prepared to invest, how long you’re prepared to wait for the benefits, and considerably more. Reading this article will place you in the position of being able to make a reasonably educated decision.

Pump It Up
The device of choice for penis enlargement, for the uninitiated, this method involves placing what looks like a large test tube over the penis, a vacuum is created inside the test tube with the use of a manual or electrically operated pump. The vacuum inflates the penis by increasing the blood flow for a period of time. The immediate benefit is a hard large erection. Lasting changes take some time we’re talking months rather than weeks. Long term results vary from individual to individual and can be affected by the quality of pump used.

The five main reasons for using penis pumps are:

1) Aiding in getting and maintaining an erection.
2) Relieving premature ejaculation and impotence.
3) To encourage better and stronger erections
4) For self-relief – some pumps have inner sleeves and vibrating bullets!
5) Gaining extra girth and length, a 20 -25% increase in girth and an extra 2 inches isn’t uncommon over a period of time.

The objective is to stretch the ligament that attaches the penis to the body. It’s the different types flasks, pumps, gauges, vibration, sleeves and more, found in the different qualities of pump that will ultimately decide how long it takes, and (possibly) how much of a difference will be made. Using a system that incorporates hanging weights would be a good idea to encourage the stretching of the (suspensory) ligament.

Swallow and Rub
There have been numerous promises quickly made (and quickly broken) about the latest pills that hypothetically induce penis enlargement. Most of these claims are dubious (in our humble opinion) at best, if not fraudulent. Nevertheless, we believe that good quality herbal preparations and creams can show benefits that are related to penis enlargement. Some of these are: Helping achieve stronger, lasting erections. Enhancing your sexual mood. Reducing the risk of premature ejaculation. Increasing libido. Encouraging an increased intensity of climax.

Many treatments contain a blend of well-known herbs that have been used for centuries because of their efficacy. Common ingredients include Horny Goat Weed (boosts the libido and supports erectile function.) Yohimbe (said to: 1.expand the blood vessels in the genitals 2. Accelerate adrenaline flow, 3. Heighten both sexual and emotional sensation. Further herbs used include
Ginkgo Biloba, Ginseng and others.

Some creams and lotions contain benzocaine and are applied directly to the penis., a mild numbing sensation occurs. This reduces sensation in the penis. Reported results indicate this helps intercourse last longer. Other creams contain various ingredients that are intended to stimulate blood flow and are massaged into the penis. This can result in larger, stiffer erections.

Lets Exercise
If you are the kind of person who is nervous about surgery (who wouldn’t be!) or doubts the efficacy of suction pumps, weights and herbal preparations ‘Natural Penis Enlargement’ strategies that use a combination of exercises to increase penis size may be the way forward for you. These exercises need to be performed regularly, up to six times weekly. Progress tends to be slow and it could be more than a year before you notice any benefit.

There are many sites out there offering these techniques, but it’s a case of ‘Buyer Beware’. Some less scrupulous site owner’s bulk out the price by offering un-necessary add-ons, shop around and pay only for what you need. Remember these exercise are merely doing the same thing that a good quality pump would do but with a lot more effort (and possibly expense) on your part.

Under the Knife
Penis lengthening using urological surgery has been done for many years now. There are also various procedures to enlarge the girth of the penis, which can add 30-50% in circumference. However it is only recently that these procedures have become even a little more popular (we wonder why?). The lengthening operation involves making a small incision just above the base of the penis and cutting the suspensory ligaments, which hold about 2 inches of the penis inside the body. The immediate 1.5 to 2 inch gain may make this more appealing for some.

As is the case with any cosmetic surgery if you are considering this option, be sure that you have a number of consultations with specialists and doctors and be certain that you know exactly what is going to be done. This is definitely something NOT to rush into.

The most direct and brutal method is surgery. You will have some gain with a lot of pain choosing this option.

In addition, the possible side effects are serious enough to make surgery too risky for any men except those with an exceptionally small penis. You can easily weak up with a disfigured penis or loose the ability to achieve erection.

According to doctors, any erected penis longer than 4 inches is usually big enough to stimulate erogenous tissue in the vagina.  A penis longer than 8 inches can ram into the cervix and cause discomfort.

Happiness does not only include business success or wealth. The bigger part of happiness lies primarily in having a partner along with a good sexual life.
Many men pay attention to the length of their penis. Many never imagine the girth of the penis when one is considering penis enlargement. The size of the penis can make some men feel insecure and less of a man, as size indeed plays a big role in a man抯 life. Despite this, many women want the girth of the penis aside from its length.

The size of a man抯 penis plays a major role for a woman as she gets her most pleasure out of it. So the importance of the dimension is just as important as the length. The woman’s vagina is equally sensitive, and the excitement and sensation are there to discover, as certain areas of her genitalia are quite sensitive, the presence of a good penis proportion makes the whole experience a lot more exciting.

The average size of a penis when it is erect is 5.25 inches, and the average length of the penis is between 6 and 6.5 inches, as shown by surveys taken from all over the world. To enlarge the penis, exercise programs were designed, and one needs to follow these programs along with certain products that will help further boost the size of their penis. There are many other penis enlargement methods available. The most accepted method is the natural method of penis enhancement because it is not that expensive, and it is also safe. There are also penis pumps which may be used to add inches to the length of the penis. Pills, creams and solutions are all over the market right now, which still has to be tested and must be used with certain exercises or devices to prove their worth.

Exercises and therapies are also available in helping you achieve the most desired results. One may observe that blood goes to the places within the genitalia were there was no blood found there before. Some of the blood vessels circulate poorly inside the penis, and exercises help a lot in circulating the blood around the genital area to make it more active and alive. Clogged veins and poor blood circulation is the reason why the penis is not as erect as it should be. While doing exercises for the enlargement of the penis, the penis size and length will start to build, and favorable results can be seen in no time.

Enlargement is generally a time-consuming method. It may take months before you see any improvements. Everything will depend on the body type and penis condition of the man in order to get the much needed results. The enhancement of the penis can be a slow process. It is very challenging to determine which methods of penis enlargement and products used for it are very viable to use and follow. Much depends on the individual, for there is no direct and general approach to penile enlargement.

Overall, having a large penis can be quite a blessing, but having a little one does not mean otherwise. The idea is to perform well. No matter what size you have, its how you use it that matters at the end of the day.

Penis enlargement pills – scam or not?

This article describes the Facts of  Penis Enlargement Pills.  A  study of all the facts is needed to come to an informed decision as to whether penis enlargement pills are worth their “salt”.

Many people wonder whether penis enlargement pills are a scam or not. Sure, none of the leading physicians has ever endorsed such a pill and some are openly claiming that this method of penis enlargement simply cannot work. Still, many men actually spend money on such pills and not all of them complain about the lack of effects. This is why the question was born in the minds of both prospective customers and simply curious people: are penis enlargem4ent pills a scam?

The answer is not that simple. The range of products available on the penis enlargement market is quite wide since demand for this type of pills is high and growing and companies stand to make good profits. Unfortunately not all companies are honest in their business and not all products are good for you. The mixtures of herbs, which the pills contain, can count just about anything among the ingredients and while some ingredients may be simply useless, other can do you serious harm.

Some of the most popular brands used to include among their ingredients Yohimbine, a substance obtained from the bark of the Pausinystalia yohimbe tree. The substance is used by the traditional medicine of Asian countries as a sexual stimulant. However, doctors have found out that this ingredient is not safe for use because of problems related to high blood pressure and anxiety.

Still, some pills available on the market (such as ProSolution Pills and VolumePills) do not contain any hazardous ingredients and have no reported side effects. The companies selling such pills have a commendably high rate of successful treatments and a large number of satisfied customers.

Our conclusion is that consumers should pay close attention to the list of ingredients, which make up each product and to the record of parent companies. Also, note that websites promoting pills featuring Yohimbine or other substances that are known to cause potentially dangerous side effects may not be trustworthy.
