Hating sex?

Is it normal for to hate sex. The thought of it makes me feel super gross. This is a new thing and only with my fiancé. I’ve had sex with other people when we broke up for a couple months and it was great comfortable and pleasant but with him it’s icky and uncomfortable. I’ve been trying to avoid it right now but I usually wake to him naked on top of me or he’ll just have sex with me when I’m sleeping and I wake up really sore down there. Now I’m pregnant cause of a drunk night I don’t remember and he takes care of me and our other kids so I feel like I should be repaying him.

Thanks for commenting. He said because we’re engaged it’s ok. I talked to a friend and she’s going to help me leave
