When I was young my dad pulled my foreskin all the way back. Obviously he did this day-by-day, it hurt like hell but damn I love the feeling it gives now Id say 16 is somewhat passed the young age so Id hit up a doc and get the snip if i were you. The pain was unbareable however, I was young and It feels good now. some might say I have an irregular penis lol...some say sexy, I say freakkkky. Gals love it
