Is he wrong ?

So my bf and I are having a baby pretty soon. I’m pregnant but besides the point I’m moving in soon like this weekend and my issue is it’s always been a problem that he constantly wants sex! Even if I’m feeling bad just completely disregards my feelings and says “his dick is bothering him he needs to cum” I like that he wants me a lot he even said the day he’s not all over me I should start worrying. But everytime I say no which is rare cus I usually give it up even when I don’t want it he gets mad! Litteraly having sex will set the tone of how the rest of our day will go. If we don’t do it I’ll get attitude from him. He would be mad all day but deny it’s because of sex like I’m fed up this is an on going thing I feel like I don’t have a choice cus I hate seeing him mad cus then he will just be a prick all day to me and it affects me. There’s no talking to him I tried and it’s like nothing. I try to tell him that I don’t want sex all the time but it comes off wrong like I’m the bad person. Now he’s off to work pissed and I’m here crying feeling like shit
