Sex Drive all time LOW !

Sooo I'm 8 wks pregnant and my SO wants either a blow jo or hand job. I don't mind or care but the way he ask is so .... rude in a way. He doesn't do some foreplay into it. He wants me to jump right in, my sex drive is ultimately low and I just don't feel like it. He says I tease to much which I don't purposely do he even says I'm "attractive" no matter what so hence he gets boners when I could be doing the most random things. But idk guys have you ever felt like this when u were pregnant . Did u feel pressured into having to do something for him? I want to but I can't force myself...
