Lack of sex life

Aliyah

So me and my boyfriend are 2 years together and we would always have sex everyday rounds after rounds but then out of nowhere we stopped and it just got worse to were we would have sex 1 times then next 2 weeks have sex and so on and so forth and I am pregnant so my sex drive is low but I still try u know but he would always want me to give him oral but when I ask he will say yes but never do it like NEVER I would have to force him and when he doesn’t it’s for 2 mins or less and I feels like crap because it’s not meaningful ... I low key feel like he will leave me because we don’t have sex & idk what to do because I deserve oral aswell just like him and talking won’t help but get me annoyed because it’s not working... any advice ? because I’m at a point we’re is literally going to tell him I never want to have sex again ... please help ..😞💔
