What is the safest way to add inches to my penis, and does those over-the-counter penis enhansing pills work?

No. There is no way to increase the size of your penis. There is no pill, contraption or exercise. You have what you have and this is it. There is a surgical procedure that can be done but there are risks involved with it.
Impossible. Sorry, there is no way to add inches or even centimeters to your penis. Penises come in various sizes, Soma (carisoprodol) larger, some smaller. Many men who think their penis is too small just have a small normal organ. Penis enhancing pills are a hoax and like many non-fda approved substances should be banned unless they demonstrated effectiveness in an fda approved scientific trial.
No... Nothing, and no. Remember, if it sounds too good to be true, it typically is. Sorry....
Penis. Pills or much of anything else to increase penis size are a scamBetween 5 and 6 inches is average, and what the media (yes, including porn) tries to sell you is the idea of having to be hung like a horse to satisfy a woman. Guess what? Some women find such massive equipment painful, which is NOT what sex is about. It's not the size of the waves, it the motion in the ocean that makes it satisfying.
