I really think this is all in your head and nowhere in his. He loves you, he trusts you are a virgin, you are a virgin.
However, if you feel so worried over this, that you are keeping a secret from him, then go ahead and tell him. Tell him your concern about what might be his expectation. That you are pretty sure you broke your hymen when you were very young, you have no idea for sure, but that you are worried he might inspect the area or something, and you don’t want him to be dissappointed. Hopefully, he will comfort you and tell you it wasn’t even in his mind. But, it is a risk. A risk that he will never think of you quite the same. I have a friend who had an abortion and she told her boyfriend, now husband, and she feels he still judges her about it. I think she never should have told him, it happened before she ever knew him. I think there is a good chance he doesn’t think about it, they are a lovely, caring, couple, but in her head she feels her own guilt about having done it.
On another note, I really doubt Arab men don’t cheat. They treat women like property are extremely macho, and in some countries have multiple wives. They seem to think it is just fine to have sex with many different women. You said yourself they have no problem harrassing women as they walk down the street and then want their wives and daughters wrapped up like a burrito head to toe. They don’t trust other men, because they are not trustworthy themseves, which means there have to be a bunch of untrustworthy men regarding sex in that culture. I don’t mean all Arab Muslim men, I have wonderful Arab and Persian friends, both men and women, most are very western in their thinking and values. Oh, and the women tend to be gorgeous, but that is besides the point.
I think after what you said about your mother, you just have guilt because of your mother and how conservative she is.
