I (F24), am struggling with my intimacy and unsure what to do about it while in a relationship with (M35)

I (24F) feel utterly and completely alone when it comes to sexuality and intimacy. I used to have a high sex drive, but after a couple awful partners I feel so terrified to be comfortable with having a need for intimacy. I’m currently in a six month relationship with a (M34). My partner is amazing. He is a great listener, funny, supportive and kind. We don’t really have an intimate relationship. We have never had sex. In the beginning stages, he would provide intimate acts occasionally. Everytime I’ve tried, he’s declined, or can’t get where a man needs to be if ya know what I mean. For awhile I was okay with that, I still am to an extent. I never want to pressure someone. But now I’m in a place where I feel close to him and want you to have that deep bond. I view intimacy highly, it should be shared with only certain people. But I fear my past partners ruined my view of myself or confidence in my own sexuality. I don’t feel desired, I never have. I feel like something is wrong with me. I try to take care of business on my own every once in a great while when I can’t repress anymore and I end up having an anxiety attack and crying. I’m just scared I am not enough for him, and with my past of cheaters my brain immediately goes to him cheating, or preferring porn over me. I don’t think that is the case knowing him and our relationship. But it makes me feel so alone, and so guilty. I don’t want to feel this way anymore

TL;DR
Long story short: has anyone else experienced sexual or intimacy trauma based on emotional abuse? How did you work on it? Is it worth even bringing up to a partner or something to keep in and hope it goes away?
