The pill

So I'm moving in with my boyfriend in a few months and up until a few months ago I was dead set on being abstinent. Yes I'm a virgin. But now. I'm 18. And. I wanna be with him like that. He's not a virgin. He was honest about that from the moment things seemed to be more relationship the friendship and I asked him. He doesn't like using condoms but he made it clear he would if it would make me feel better. But I don't want to... And I know that's probably a horrible thing and I don't wanna get pregnant. But I really wanna be. With. Him... So I'm really thinking about getting on the pill. And in all honesty. I'm kind of scared... I've never done anything more then a bit of making out. He's only my third boyfriend. But. I know he's been with women and I'm afraid that I may do something wrong or just not be good at it and he'll start thinking of other times with other girls because I don't have the experience... Could honestly use some advice about both things.
