OK. The only thing I can say about this is that most people here are right, but not really. I must admit, you 2 are clearly different from one another when it comes to sex. If he is the one you want to marry, one of you will have to adapt, and I don't see him changing any time soon. Truth is, unless you're in an open relationship (if you're not satisfied with sex go and have sex with someone else, it's fine), then he will either keep hurting you, or cheat on you. That's the harsh truth. If a couple is to succeed it has to be compatible in certain ways, and sexually is one of them.

He is not right to hurt you, but maybe that's what he likes. Some girls like doing it rough, others like it soft. Some guys like stuff that to me are absolutely minging but to them is paradise. But honestly, you want to marry him? Enjoy it. You can't enjoy it? Ooopsss forget about marrying him, just find someone else. It's better. This is because he doesn't have any regard, 'ok sex' is not enough. In order to have a healthy relationship you need a good sex life. And he won't give it to you unless you enjoy it harsh and rough
