I don't turn him on...

At least that's how I'm feeling lately. He never says I do and when I say that he turns me on he'll say I know. He'll call me sexy. When I send him a picture of me in lingerie he says I look sexy or compliment my butt but the conversation kinda goes dull and in person he doesn't seem too interested. When we have sex I'm usually the one initiating it. He calls me annoying when I do try to get him in the mood. When he shows no interest I'll stop trying to have sex but then he'll ask why I stopped touching him/whatever I was doing. That's confusing. Sometimes I feel like he just doesn't want to have sex with me.
