Suddenly can’t orgasm

I’m 24(F) and my partner is 22(M). We have sex like 1-3 times a week and for the past year he’s gotten rlly good at eating me out, to the point where he can get me off in like 10 minutes. Well now it feels like we’re back to square one bc he hasn’t made me cum in a month, and I feel horrible abt it. I don’t watch porn and don’t masturbate so it can’t be bc I’m desensitized. I just don’t know, I feel like my body is failing me. I am disappointed that I haven’t orgasmed in a while, but I’m even more worried about my partner. We both have low self esteem at baseline and if we feel like we’re not meeting each others needs enough, it becomes a spiral.
Anyway I’m not on any meds but birth control pills. I’m a high strung person by default, so I feel like stress and anxiety can’t be it. I just don’t know. Any advice or just relating would be appreciated ^-^
