My boyfriend doesn't wanna have sex with me anymore!!!

Ok so me and my boyfriend have been dating for 2 years now and have a had a really healthy relationship, however recently any kind of affection that I try and give or try to receive he like downs it! Like it's been about two months he hasn't wanted to do anything and you have to understand we went from doing it like 5 times a week to now I have to wine to get him to kiss me. And then he makes me feel like a needy horny slut just because I want it! And so I just am tring to ignore it but I also feel rejected and like I've tried to not mention it maybe im not enough to of a chase for him anymore that doesn't work ! And it also makes me feel like maybe I'm not attractive to him like I was before but we've been together 2 years and he's seen me at my worst and still been a loving boyfriend idk why all of a sudden he is being like this idk are there any other girls who have this problem with guys not wanting it?!?!
