My boyfriend is becoming increasingly comfortable with me. Which is normal because we have been together for a few months now and if he otherwise wasn't comfortable already I know there would be a problem. When we are together he can't keep his hands off me. We kiss a lot and he feels my ass and runs his hands up and down my legs and my body and he'll sometimes even smack my ass too, not hard but playfully. When we kiss he sometimes will moan or he will pull me into him or squeeze me really tight and breath quickly and deeply. He has told me before that he finds me irresistible. For the first time the other day he asked if he could see my breasts and I allowed him to and then he started kissing and touching them. Everything is progressing in our relationship and it is obvious that he wants to have sex with me, and I do want to have sex with him as well. We are both virgins and I'm 17 and he's 16. I want to talk to my parents about birth control but I would like to know the best way to start a conversation about that because it will be kind of awkward to talk to them about this but it is so much better than becoming pregnant.
