He makes me so mad sometimes.

A👸🏼
So my fiancé and I have been together 1.5 years. (We recently got engaged on May 7th.) I don't know if it's just me but we rarely ever have sex. When we first got together we had sex almost everyday and now it's once or twice a week and it really seems like it's only when he wants to have sex. He recently told me that he feels obligated to have sex with me. Like what the hell? He said that he feels like if he tells me no to having sex then I get mad and that's not what happens! Yes I get mad when he says no but that is only because he PROMISED we would have sex and I know that sounds stupid but c'mon don't promise and not go through with it. He gets mad at me when I even try and be sexy for him. For example, last weekend I wanted to surprise him by buying some sexy lingerie so once I got home I casually went and put on what I bought and walked out of our room and the first thing that comes out of his mouth is "I don't want to have sex. Can we go take a shower?"🙃🙃🙃 Its just annoying how anytime I want to have sex he gets mad at me for trying/asking but whenever he wants to have sex we always do what he wants. And it's just like when it's that time of the month. No we don't have sex but he expects me to either give him a handjob or a blow job but he NEVER does things like that for me. And if I tell him no then he will go and watch porn.
