Am I just not appealing?..

My boyfriend and I have sex maybe once a week. I try to pursue more than that and he turns me down. I have t initiate most of the sex (unless we’ve been drinking). It’s really starting to shoot my confidence down...even further than it already is (I’m a bigger girl..he’s skinny). He always says it’s because he needs to sleep for work (he needs 7 hrs or he doesn’t function 🙄...what id give ...lol). We don’t really have a lot of time between when I get off of work and bed time, tbh. I guess this is more of a rant than anything. Ignore me. Lol
