I've been seeing this guy for a while now (I'm 16 if that's important) and I really like him. We were talking and he says he wants to go down on me and like, I'm cool with that...in fact I really want him to. But I'm feeling really insecure about my vagina. Like I don't want it to taste bad or anything. He's done it before and I have like basically no sexual experience. I would just like to know how i can..."improve" my vagina I guess.
