Just venting... :/

I’m feeling really unmotivated and insecure because my boyfriend doesn’t seem like he wants to have sex with me. I always have to start it. When we do have sex it’s always about him. He hasn’t done anything to pleasure me in years. I either give him head or he bends me over until he cums (literally lasts not even 5 minutes....) He knew I was upset last night after we had sex. I told him I wasn’t and just brushed it off but i’m really starting to just want to give up. We have sex maybe twice a month..... idk what to do.
