Sex isn’t the same with him... help ?

Ik how to have sex & Ik how to make my man cum, and everything like that but recently i’ve gained some weight, not too much to where i’m really big but i’m way bigger than the start of our relationship 2 years ago and I feel like my man recently hasn’t been enjoying the sex as much.. he was never the type to really moan and go crazy but even more so now I feel like my pussy “changed” (I know everyone on here says it’s impossible for you to get lose or your vagina to stretch lose but in my head i feel like it has gotten lose)

? or something’s different or maybe my extra belly area is a turn off? idk.. I’ve brought up the fact i don’t feel like he enjoys it, and he said that i’m crazy for thinking that.. He isn’t the type to tell me i’m day or anything either, he likes my belly and thighs and ass.. Idk, anyone else go through a rough patch like this and feel like your S.O isn’t enjoying sex as much anymore? He’s always horny though and always up for sex, and my sex drive is no where near as high as his either..
