Anyone who thinks that working out will affect your cock in any way isn't that smart. On a sidenote, more people need to realize that doing the splits doesn't stretch your cock. I've dropped down pretty far into the splits in front of people, and watched guys grab their crotches imagining intense pain.

And I've actually been asked by one girl if I broke my cock from going too far into the splits.

People...

Also, anyone who thinks that a guy has a small cock just because he's muscular isn't that smart either.
