My partner has been asking me to perform sex acts on him that I am not comfortable with, I have done them because he wanted me to try despite my reservations but now he's saying that I am not 'into it' enough and need to do more and that I am not listening to him, I don't care about him and I'm selfish. He doesn't stop talking about it, and he says that he's spoken to his friends who agree that they would do things for their partners and he would do anything I wanted me to do and so I am the selfish one who needs to try harder. I tried to explain that Im not comfortable and I don't want to do these things and he gets really angry telling me that I'm just not trying hard enough. He says that because I have agreed to do these things already I can't now change my mind.
It doesn't help that our sex life in general is pretty rubbish at the moment, I am on antidepressants and have no sex drive and even if I did I have been bleeding constantly for 4 weeks now thanks to my contraceptive so everything is based around him - which admittedly isn't his fault and it probably is very selfish of me that I don't initiate sex more often. He says that he's just trying to help me by putting pressure on me because I need to get out of my comfort zone, that it will help with my depression and uses non-sex related examples of this but I feel like sex is different, and that I should be comfortable!
I'm pretty sure if I don't do these things then he will find someone else who will, he says that he won't but certain comments he makes say otherwise. And the fact that he has said that he has mental health issues as well and this will help him, but because I won't do them I'm making him worse. It hasn't always been like this, it's got worse over the last couple of years and now it feels like it's all he ever wants to talk about. I ended up breaking down in tears last night saying that I didn't want to do something and he's said that going to give me a break today so I think he feels bad about it but I know it will start all over again.
