What to do

I’m 4 months pp with my second son. Lately I haven’t been in the mood to do anything with my husband. So last night he asked me and I told him I’m wasn’t in the mood I’m sorry but I’ll play with it. He said fine. While we were doing that he told him to take my pants off and just to sit on it. I told him no I don’t want to but he took my pants off for me and lifted me up to sit on it. After that I I told him I wasn’t happy doing that but he doesn’t see anything wrong. Was it wrong he had me do that?
