My boyfriend said he would love to finger me. But there is no pressure. Thing is he wants me to shave that area to do it.

I have no idea how to do that! with a razor? Wax!? I have no clue. We've been going out for three months so is that too soon? And what if (if i let him) when he does it discharge or blood comes out? That would be really embaressing. How do I guide him to do what feels good and not what hurts? I shouldn't but I'm really paranoid about my body... and my legs and bum have the worst stretch marks on them ever. I don't think he'll mind at all because apparently I'm perfect. But it would be the first time we did something like that and what if he is shocked with how I look without clothes!? I like him so much and I want to be able to let him to do that to me because he said he would love to but how the hell do I shave down there without leaving marks or stubble?
