How old are you!? I'm going to write as though you're 18. At this point, you should be fully aware of your body and what you want to do with it. First, I would discuss the whole sex thing to begin with. And let's not have this be a double standard. If this guy does want you to shave, he should feel obligated to reciprocate. This goes for anything he may want you to do. Sex takes 2. Now, on the literal subject of shaving. Today, shaving is seen as hygienic. It reduces sweat and odor in the gential area and look more, say, aesthetically pleasing. However, this doesn't mean you should go bald-- real men understand the attractiveness in a neat above-genital tuft of hair and won't settle for rubbing up against what feels like a little girl's vagina. Just neaten and trim it up so it's short and even-spread. Dangling loose hairs on or right around the labia looks gross and feels even more gross when performing oral sex so do away with it, but keep the hair above the vagina and, as said before, trim it up.
