What would you do?

I'm 26weeks pregnant with our 4th baby and my bf and I got into an argument because he wants more sex. I however don't want more sex because he's always to rough. If I let him have control in bed it hurts and I'm raw for days after, and it hurts to walk and everything is all swollen too. His argument was it's my way or no way he never gets to be pleased the way he wants to be. But I always tell him we could do it his way but it hurts me (he's over 6 ft and 300lb I'm barley 5ft and while pregnant I'm just starting to push 130lbs) and he never listens to me when I say stop. And when we do it my way hedoesnt have trouble walking after or is in pain after either.

So last night I gave him what he wanted and he got to have more control in bed. And like I said would happen I'm on pain. Well I was in the show this morning and I was cleaning myself . Like I said this isn't my first pregnancy. So I know how things work. My cervix was SO low and soft. And there are normally bumps on it. I've passed all the blood work and physical exams during early pregnancy too so I feel like I'm just stressing over nothing. Because there's no discharge, no odor, no itching or pain out of normal. My Dr during my last pregnancy told me the bumps were cysts and normally people don't even notice them and the go away on their own... But also I don't know if there are warts? I would think that if they were warts they would be more than on my cervix? Should I ask my doctor during this pregnancy to take a look to make sure there is nothing serious? Also what would you do if it was your S/O that was complaining after 9yrs and 4 pregnancies about "boring" sex. I've been telling my Drs for weeks I have so much pressure in my pelvis and vagina area could this be related?

Like personally we met when we were 19...we're both almost 29. I feel like he needs to understand love isn't about sex and sex shouldn't be painful. And we don't need porn start sex EVERYTIME. Because he likes it super rough for a long time. And I don't enjoy that because I know it's gonna be painful during and after. Especially during pregnancy!!!
