Boyfriend hates having sex with me

We’ve been together almost a year and a half. We have sex MAYBE 1 time a week, sometimes once every two weeks. I’ve voiced to him that it upsets me, but no change.

I had a sexual trauma to me at a very young age. It effects me still at 22, but not too bad.

Whenever I’ve tried to initiate sex with my bf, I get rejected (literally 4/5 times I try) but it’s not just a simple “no, I’m not in the mood” it’s always that he’ll lead me on to think we’re going to do it, he’ll play into it, but then when I’m ready and really want it, he just goes ‘no.’ Very rudely.

The other day I was trying to initiate it, but I didn’t know what to do, and he told me “it’s not rocket science, *my name*” very aggressively. It hurt my feelings so bad and it embarrassed me and came with so much shame. I’m tired of feeling like this. I’m tired of no sex. He claims he’s still into me, but that I don’t turn him on.

What can I do, what should I try? I need help :(
