am i wrong for thinking this is weird?

My bd is very into sex whereas I’m not really. And more so not in front of the kids. But this guy just doesn’t care. He’ll try to put his hand in my pants, try caressing my breasts, pretend to thrust whenever i bend down or anything, wants me to sit on him, and just all this shit and i don’t like it. especially with the kids like it’s so weird and icky to me. and i constantly tell him to stop and he doesn’t until i yell at him and get away. then he calls me names like it is weird! our kids are 1 and 4 but it’s still so weird to me. i don’t even want to have sex in the same room while they’re asleep. am i wrong for thinking it’s weird to do that in front of the kids?
