1: no, in fact a lot of women don't
2: no. sometimes using a tampon or even really strenuous exercise may cause your hymen to tear (all our bodies are different so what may cause tearing for one female may not for another), meaning you will not bleed your first time even if you've never had sex.
3: nope, same as above.
4 5: you may or may not, depending on your body
6: basically once its broken you will not likely bleed during sex, however some people spot anyhow after sex so its really hard to say
7: not sure how to answer that. If he's well informed he will know that not bleeding during sex doesn't mean you're not a virgin.
***Keep in mind that if you tell him you're a virgin and he doesn't believe you, you might want to rethink having sex with someone who doesn't trust you
