Losing virginity

Is it normal the only reason i don’t want to lose my virginity is the the fact that I’m worried about what the guys reaction is going to be once he sees my body? Ofc there are other concerns that come with losing your virginity but I’m getting to that age where it’s relatively normal to have sex with your boyfriend. I’m scared once I get one he’s going to want to have sex. I’m okay with it as long as we are together for a while. The thing is, I am so worried he is going to be disappointed with my body. That’s the reason I don’t want to have sex. Is this normal?
