Boyfriend gets upset when we don’t have sex

I have a low-ish sex drive, and I experienced sexual abuse in the past, and I’m on BC that lowers my sex drive even more, so I don’t feel like sex a lot of the time. My boyfriend often gets upset when we don’t have sex. I try to prepare myself to have sex at least once a week, but sometimes we’ll skip one and he’ll become really upset, and basically pout. I understand sex is important, but once a week to once every two weeks is normal to me, it‘s not to him though. I also kind of dread sex because when we do try, he’ll barely get me wet enough just to put his dick in and it’ll be super painful because I’m not wet enough. He’ll suggest lube like it’s normal to not give me enough time to get turned on, and lube is fine. I’ve brought this up many times but he doesn’t really understand, and keeps shoving his dick in dry. I don’t know how to bring it up again
