Fiancé says I turn him off because I pressure him to have sex
My fiancé 35 and I 33 have sex once a month if I'm lucky it's twice. This has been going on for 6 months now. We are saving for our wedding in 6 months. I spoke to him three times already telling him I felt hurt and that I didn't feel sexually desired by him and he first told me he felt tired/stressed/pressured to have sex. The second time I brought it up to him and said you have to be watching porn and jerking off because it can't be that you're stressed tired to not jerk off. He said that he felt pressured like sex was a job that he felt turned off because of the pressure I gave him. I said we can watch porn together, he said no. I have not said anything to pressure him for about a month now. And nothing.
This morning he woke up earlier than usual and I woke up as well. I stayed in bed he went to the bathroom. I hear a girl moan and he pushed the door closed. He was def watching porn. So I said "hey you okay in there" he said "yeah I'm okay" he came out of the bathroom asked me what was wrong. I said Joseph we haven't had sex and I hear a girl moan?? I'm right here! We could've had sex? He flipped out said that I stress him out that he was watching a movie on Netflix. I do not believe him. He said that it's always something with me and left angry.
I don't understand what's going on. I'm scared that this is what it's going to be married?? How do I stop pressuring him I'm not even sure what I'm doing wrong!
