My bf and I have been having sex for almost a year now, using the pull out method. Nothing has occurred and I got scared once because my period was late.

I am about to start BC. He’s excited because he wants to cum inside me. He’s done it with past girlfriends. I never have, should I allow him to? I feel like I’m just scared because of the unknown, since I’ve never done it before. I’m scared of BC all and all because I hear about the side effects. I’m a pretty healthy person and I don’t want to change just so my bf can cum inside me
