What’s my risk?

Bianca

I’m 15 and my boyfriend is 16, we’ve been dating for about 6 months. Were both super attracted to eachother and I’ve sucked his dick and given him a handjob and he’s ate me out and fingered me. But lately while we’re doing one of those things I’ve been wanting his dick inside me sooo bad like I’m just craving it and want it to happen. He says it’s my decision and he’s fine with what I choose because we almost did it yesterday but he stopped to ask if I wanted to or not. I think I’m ready im just so nervous because I’m not on the pill and my parents don’t want me on it. Him and I talked about how we would use the condom and pullout method but I’m still scared of getting pregnant. Should I just go for it and have plan B ready just in case. How high is my risk of getting pregnant?
