That is about half the total skin of the penis.
I didn't know it was perfectly normal because I had no idea what to expect.
The outer foreskin layer contains nerve endings which respond to gentle touching during the early stages of sexual arousal.
When the penis is not erect, it tightens to narrow the foreskin opening.
But here's the tricky part: Neither one of us knew that.
For some men, so much skin has been removed that erection becomes difficult and even painful.
