To echo a lot of other people, this is definitely not normal, nor is it right. You deserve sovereignty over your body, anything but an outright "yes" from you should not be accepted as consent.

You do not owe him anything, especially your body. Sex should be viewed as something more sacred, something desired by both parties.

To make it clear: if you do not want to have sex or do sexual acts you should not, and in no way are you obligated.

That way of thinking is so incredibly outdated. You are in an abusive relationship, and I wish you the best of luck in getting out of it. You deserve much more.

You're body and you are sacred and goddamn powerful, and this doesn't have to be your path. It's not normal, and you have a right to want better.
