Does every virgin bleed on her first sex?

Well, I was a virgin but I didn't bleed when I had first sex with my boyfriend. I don't understand why? Could someone explain me? Because I didn't bleed, he doesn't believe me that I'm a virgin. I don't know how to explain him and it was a really tough time for me. Now, I've broken up with him and everything's fine now. But I still want to know why I didn't bleed although I'm a virgin.
