So I'm 14, 15 in July and my best friend (guy, 15) and I have this sort of FWB thing going on atm, and I really want to lose my virginity to him but is it too early to have sex?

Also, what are the chances of me getting pregnant? Bc we have both discussed it and neither of us ever want kids so that could really put me off. I know if I was to get pregnant I'd be too scared or embarrased to do anything about it 😅 Is this a sign that I'm too young?
