I've read several of your questions regarding sex, and it's made me really worry about you. Don't get me wrong, I don't know you or your situation, but he sounds extremely insensitive and inconsiderate. Pressuring you to preform oral sex on him, having rough sex with you to the point of tearing your vaginal tissue despite the fact that it's painful to begin with?! I understand that pregnancy can be a rough time on a couple's sexual relationship. For a man, he may not see why his needs shouldn't be met. For a woman her body is changing, and her intrest may increase or decrease. But a GOOD man should understand and be sensitive to you and what you are going through. You have a developing human life growing inside of you for crying out loud! Do not be afraid to put your foot down. You do not deserve to be treated like some sort of on demand sex object. It's not like you are going to be pregnant for ever, tell him to suck it up and shut it. Best of luck to you.
