HELP! Virginity!!!

rose
Ok so I am 15 and I've always wanted to wait for sex.. but idk now I'm feeling different about it. I've told my bf about how if we do have sex I want it to be later. I don't want to rush into things but I don't want to wait forever at the same time. On the other hand I'm kinda scared to have sex. Is that weird? I mean I'm not scared of the thought I'm just scared I'll mess up, embarrass myself, or hurt him. Idk... YOLO. Is 15 to young to have sex???? Please help me 😔
