I'm going insane... please help.

My fiance and I have been having some issues with sex lately. We used to be on the same page, and when we first started having sex, we made things very lively and kinky. But over the years, our sex life has changed drastically. Now it's much more vanilla, and I noticed my fiance just having an overall

disinterest in sex. It seems like now all he wants is for me to blow him and then have sex and get it over with whenever he's horny, and he doesn't really have a high sex drive. I do have a high sex drive and I have a lot of issues with orgasming... those issues being that it seems like I just can't orgasm. So I'm always left feeling really sexually frustrated because I'm never getting off. We live together so I dont really do much masturbating, and it never feels as good as when he does it. It doesn't seem like he cares about sex much though, doesn't really care about trying new things, using toys or foreplay, fuck he doesn't even really care when I wear lingerie for him. Recently, when we talked about this he said he wanted me to initiate sex more often. Last night when I tried to initiate after he had already started teasing me, he physically removed me and then started kissing me very innocently and told me he loves me. While I have no problem with respecting his boundaries and backing off when he doesn't want sex, I find it really hard to initiate now. Because of some past experiences, I get really anxious about sex and I have a difficult time being dominant and initiating, as I'm just generally very submissive. So it's been difficult to initiate because I'm feeling rejected every time, and I feel like I don't really have the right to feel that way either. I can barely even talk to him about it because it makes him super self conscious that he's not pleasing me and he gets really sad and neither of us know what to do. Usually the conversation goes in circles and we just end up back where we started. Please help us! I love this man so much and other than this our relationship is perfect. He's honestly my soulmate and I will marry him even with all this, but I would like to fix it. I just don't know what to do. Please help! I'm losing my sanity :(
