Unsatisfied

Ladies. What are you supposed to do when you’re sexually unsatisfied? I’ve been with my FIANCÉ for almost 3 years, as of the last few months we have sex once every week-two weeks. I’ve asked if he’s not into me now, not attracted to me, whatever else. He says he’s still so into me, I’m so sexy, ect. Yet hardly touches me. I’ve told him i want more. Even tonight, and he said okay we’re gunna have great dirty sex. Then on the way home says “oh I’m so tired. Oh I’m so sore from the gym. Oh I’m so hungry.” Which all means I’m not getting shit. Like what am I supposed to do?!!? Cause I’m over it, over begging and wanting him constantly and getting nothing. Should I just get over my want? HELP.
