anxious because boyfriend thinks he knows for sure that I'll bleed during sex

I've been with my boyfriend for a little over a year now (also we're long distance) and I think I'm ready to let him be my first time soon. It wouldn't be his first time though. I'm a little nervous because he has it in his head that every girl bleeds a little when they have sex for the first time. What if I don't bleed and he thinks I've been with someone else while he has been away? I do touch and finger myself (he knows I do) and I'm worried that would make me not bleed. He's a nice guy and I'm probably just worrying over nothing, but I'm still nervous
