I want to have raw sex with my boyfriend but...

I'm not on any contraceptive (I know I need it but I fear what they'll do to my body and mental state) but like my bf wears condoms but loses erections so fast when he wears them, its frustrating. He has had sex the majority of his life raw, (he is a 26M and I am a 19F) but with me he insist on wearing condoms (even tho he has stated he wants to do it raw with me). I know its bc of a past issue but I can't help but fiend for it. I've never had any sexual experience with anyone else but him, and as much as I love him I want to feel satisfied sexually too. But I dont want to have a baby or anything..I'm in school. Maybe if I get on BC, would it be okay for him to have raw sex with me if he pulls out? Idk what to do about this feeling...its bugging the mess out of me.
