Howdy!
I am 22 years old, and over the last 4 or 5 years I have noticed my foreskin failing to stretch over the head of my penis when erect, unless gentle coaxing or sheer determination is used. After vigorous sex or masturbation, the stretched part of my foreskin often tears and chaps, leaving it both painful and unpleasant to look at.
It's starting to get a little annoying. Is there anything I can do?
