How am I suppose to feel!?!

So I had my third baby through csection this is also my third csection it’s been 6 weeks and I also recently got the mirena iud and feel these uncomfortable cramps so for since I have given birth my husbands keeps telling me he wants to do all these different positions (I know tmi) but I told him for a while we might only be doing missionary because it hurts and it’s going to take a time to recover and he always has to bring up how boring it is and that it’s not enough for him and honestly I’m tired of it like you try having three babies and just had a baby 6 weeks ago and you tell me I can do all these moves like I’m not the same and at this point I don’t even want to do it all I’m gonna be thinking is if he is even into it or not and make me feel insecure
