please help. I'm so damn sexually frustrated 😭 please read it and hang in there

Just needing a little rant and wondering what you ladies would do. So to start off, I am extremely self conscious of my body and weigh. My SO knows about it but I definitely try not to show it since "confidence is sexy". He's really into big prob star asses (you know what I'm talking about) and I have the complete opposite of that... Anyways... he's a very sexual person, we both are. Love sex.. love everything about sex. But the past couple months he never wants to do anything. For example maybe a month ago I was trying to turn him on and he jokingly said "if you were wanting sex you should have put it in the schedule" 😔😒 it bothered me for a few day then I finally got over it. So for Valentine's Day I got some lingerie and anal toys since he's super into that thinking he would want to start using them and doing it every night again but we used them on Valentine's Day and that's it. Last night I told him I was super horny and tried turning him on and he said "we will tomorrow"... okay so I've been horny all day waiting... so I picked him up from work and we got home I tried "messing around" and he sort of stopped it and said we should go on a walk since it's so nice out..... so we did and now we're laying in bed and I tried to start something and he said "well we should've earlier but we went on a walk instead" then said "I promise we will tomorrow"
