He shouldn't be pressuring you to have anal sex when you don't enjoy it (I don't either).
That is sexual coercion.
Coercion is actually a crime.
He shouldn't be trying to accidentally on purpose trying to start anal sex when you don't want it and haven't agree to it, that's a type of rape.
Sex is supposed to be enjoyable and feel good for both people.
You could get some reliable contraception to prevent pregnancy from vaginal sex .... If you keep having sex with him, which I honestly don't think you should.
He had no right to control what you wear and walking away from you because you wore something he didn't like is controlling, rude, disrespectful, bad mannered and nasty
That is also a type of coercion .... Treating you badly so you'll obey him.
It's no excuse that he's a Muslim.
Muslims aren't supposed to have sex outside marriage but he does that no problem, right.
Personally I also don't think relationships and marriages with between Muslims and non Muslims in most cases
This guy sounds like a sexually coercive, selfish, controlling, nasty user and i wish with all my heart you get away from him.
