does anyone knows how to enlarge your penis . i want mine bigger, its only 6 inches long when hard?

Question

there must be somr kind of excercise you can do or something

Answer 1

there aren't any gadgets, pills, attachments, exercises, creams, injections, or pumps that can permanently add length or width to the penis. they're all fake, phony, and expensive.
try accepting your 6". as long as it works and gives you the pleasure it was designed to, then have fun with what you have.

Answer 2

No, there is no exercise guaranteed to increase the size. If you havent crossed the growth stage, then it might increase a bit.
Why do you want it to grow longer? 6" is more than adequate for any purpose that can be thought of. Did someone tell you that your size is not enough? If yes, just ignore such barbs and get on with life. There are other things to concentrate on and spend time, than penis size, in your case.
