Would wearing tight underwear for most of your youth discourage penis growth? -

Just wondering if wearing constricting underwear for most of your youth would impede the growth of the penis.

Nope, not at all. Genetics and some people say use, but not underwear. Tight underwear however can hamper the production of healthy sperm. Kind thoughts, Reyn

NO, most of the adult male population of the US wears briefs and have since childhood, and most have perfectly full size equipment.

No, but it will make you sore! Next question.

Your penis will grow to its adult length on its own, regardless of what you do. Tight or loose underwear has no effect on it.
