the gyno told me she'd seen so many girls coming with in grown hairs that have got infected and created problems in their outside bits....why would you shave down there, we're meant to have hair down there to avoid friction. a little trimming is good to keep it neat, but full shaven 6 year old girl look is a bit too much i think.
i'm not into the clean look for men-- though it can become annoying when they're so underkept.. choking insodents have occured in my time..
Trimmed is nice. Just so it's not like burying your face into bad 70's shag carpeting, that happens to smell like a nutsack.
