Just don't feel it :(

My hubby and I have been together for 6 years now and a little while before we started dating, I started noticing I didn't want sex as much as usual. I didn't think much of it, but it never came back. I'm 27 now and I've tried everything to get my sex drive back with no results. It's not birth control because I've been on 3-4 different kinds, off it, and now I have an IUD. It's also not the relationship and 'just being bored' because I don't even feel sexually attracted to other people. Now it's affecting my relationship because he wants us to be passionate and I know he wants to feel wanted. I just don't know what to do anymore 😭Help!
