Exercise your pelvic floor. You may not be able to build up the penis itself through exercise, but if you strengthen your pelvic floor your body will be better able to hold blood in your penis. The pelvic floor presses on the vein that keeps blood from leaving the penis during erections. You can strengthen your pelvic floor using Kegel exercises. A trial conducted in Britain concluded that men who performed Kegel exercises experienced better sexual function than those who made other lifestyle changes but didn't perform the exercises.[8]

Even worse, many of these pills contain undeclared substances to make buyer believe the product works. There are hundreds of different so called penis enalrgement pills on the FDAs official “Tainted Sexual Health Products” warning list, including some very well known and popular pill brands. The hidden drug ingredients are often Sildenafil (Viagra), Tadalafil (Cialis) or Vardenafil, subtances used to treat erection problems, short ED (erectile dysfunction). While these prescription only drugs can help patients suffering from ED, they can also have dangerous side effects and interactions, especially for people taking certain cardiac drugs. In the worst case, they can cause heart attacks, there are several verified actual deaths related to dubious penis pills. Don’t risk your life and stay away from enhancement pills, no matter how tempting the advertsing or fake reviews sound. My advice: Go for effective natural training instead.
If you want to increase your penis size, lose your weight immediately if you are overweight. When you are fat, your pelvic region may be hung over. And when you are obesity, you may have a small penis as fat around your penis can stop your penis growth. If you lose weight, you will see that the bone through the penis will be smaller and your penis will be seen bigger. Actually, this is one of the best tips on how to make your penis bigger naturally at home that you should know and then try to lose weight for good.
A numbing cream, followed by an injected numbing agent, prevents pain. “Depending on the patient’s goals, a filler is chosen and then injected into the corpus cavernosum of the penis [two columns that contain most of the blood during an erection]. The filler is then worked through the penis, to achieve a uniform increase in length and girth,” says Cedar Grove, New Jersey, physician Dr. Muhammad Mirza in a RealSelf Q&A.
Definitely yes, if you have a big or small penis is mostly defined by your genes. Sons of men with a large penis often have a large penis. Sons of men with a small penis often have a smaller penis. There are certainly exceptions, but in general genes are very dominant when it comes to erect penis size. From my own experience and research, genetics are the most dominant factor in size, environmental factors or lifestyle only have very limited to no effects.
The average flaccid penis is between 3.5 and 5 inches long and 3.5 inches around, while the average erect penis is a little more than 5 inches in length and 4.5 inches in girth. Some men feel inadequate, even though their penis size is perfectly normal. Nearly 70% of men say they’re not happy with their size, and about half wish they could be larger. 
Manual penile exercises can be done without the need of special equipment. However, if you add extenders or pumps to a workout routine, you can enhance your gains. For beginners, it’s recommended to do one of the beginner-friendly exercises first (like stretching or jelqing) for a few months before doing combination routines with equipment. This ensures the penis has been fully-conditioned for the additional load caused by extenders or pumps.
Stretching with weights. Weights or stretching exercises won't bulk up your penis -- it's not a muscle. But hanging weights off your flaccid penis may stretch it a bit, O'Leary says. The catch is that it requires a freakish degree of dedication. "You might have to wear a weight strapped to your penis eight hours a day for six months," says O'Leary. At the end of it, you could be lucky enough to gain about half an inch. Risks include tearing of the tissue, burst blood vessels, and other problems.
