I've always kept myself bare except for a small trimmed patch up top for 3 reasons:
1) Hygiene
2) I prefer to be bare for my "alone" time - I don't want to fight a jungle when I'm rubbing one out.
But most importantly:
3) I prefer a woman that is freshly shaven because I like the look, I think it's more hygienic and I hate hair in my teeth.
If I'm expecting my date to be freshly shaved, it's just simple courtesy to give her the same because as some of you ladies have already stated you prefer a shaven man for the same reasons I like shaven women.
A good no razor burn shave cream, a brand new high quality razor while in a steaming hot shower always works well.
