Virginity

Okay so , I’m 18 years old and honestly I want to lose my card. I wanna do it with my boyfriend and I feel ready finally but my biggest issue is my fear of getting pregnant so that’s why I continue to participate in abstinence. Loads of my friends have lost theirs already and seem to not ever have this fear, which leads me to believe that maybe I’m just over thinking. Ofc I wanna get on birth control before any of this happens, and I want to make sure we’re safe. But am I just paranoid about the whole situation? I’d like advice on my situation, or maybe tell me y’alls thoughts before and after having sex. Thank you for your time & responses :)
