I am 19,I shave it all, except for my chest and I keep around my belly button trimmed up looking nice. It doesn't itch anymore it did the first few times...I like it a lot better, it makes you look more clean when you shave. And the two girls whom which I have had sex with both told me, "I hope you shave down there" I was like of course..and they said "good, hairy is gross." I just imagine if I am having sex with a girl, she doesn't want to be rubbing up against hair or giving a BJ and getting hair in her mouth..ew . But that's just me, the times have changed and guys are shaving it off and so are girls.
