Getting eaten out

Okay so my boyfriend wants to eat me out. I would really like for him to. But I always get so paranoid. I always wonder if I smell or taste good. The last thing I want is for him to get grossed out. Also, nobody has ever seen me down there. What if he doesn't like what he sees??? Please help!! Any tips on smelling and tasting good down there???!? P.S I'm a virgin lol this is all new to me.
