Lol. Okay, first of all not all women bleed their first time. Nor do all women have a hymen. Lots of women, by the time they are sexually active, have already lost their hymen in a period. Some do not ever have one at all and others are lost young simply from being active. (not sexually, physically)
if he is a virgin also, he cannot tell. He may wonder, but will not know for sure.
Also, the hymen is not what causes vaginal tightness, so even if he breaks your hymen, your vagina will still be quite tight as it has not ever been penetrated before. You will eventually relax and will "loosen" up, but your hymen has nothing to do with that.
I never bleed and obviously didn't have a hyman as I was very active as a child. But, I assure you I had never had sex and if anyone had questioned my virginity I would have surely not married them! You have to have trust in a relationship. Is he a virgin? If so, then okay, I can see why it is so important for you to be, but if he isn't then why should you be?
