i wish my gf (25f) found me (22m) sexually attractive

hey guys, i’ve been dealing with some dissatisfaction in my relationship (in more contexts than just sex) for a while, and I’m not sure what to do about it. we have been together for a little over a year and a half. for context i’m FTM and on T, so i have a high libido. in the beginning of our relationship, we were having sex multiple times a week, and it was amazing. i told her so, that i loved it, and back then she was really into it too, or so i thought. she was even ready for sex before i was, and initiated many times back then. fast forward to now. it happens once ever month or two, and the last time we did something she told me that she felt nothing. as hurtful as that was i comforted her and talked to her without making it about my feelings. over the course of our relationship it started happening less and less, and eventually i asked her if it was me, or if not then what was up. she told me that she just rarely actually feels horny, and the thought of sex doesn’t turn her on, only occasionally when something happens first does she get horny. i asked her why we did it so often in the start and she said she felt like she had to, and essentially played it up. now part of me is hurt by that, feeling a little tricked. but i also understand that feeling pressured must have been awful. she did tell me that i didn’t make her feel pressured, it’s more of a societal norm thing. she also at one point made it sound like the low libido was a result of her worsening mental health, but then in another instance she made it seem like she will just always be this way. now i’ve been trying very hard to get over it, because i don’t want to be that guy that thinks sex is all that matters in a relationship, because it’s not. however, it is important to me, and it’s becoming harder to just go months without, especially when i rarely have any alone time to take care of things myself. i’ve told her how i feel and it turns into a complicated discussion. she does care that it’s hard for me, but i don’t know if there’s anything we can really do to change it. she’d have to force herself to do it which apparently she had been feeling more like that a few times, which makes me feel awful. all this has made me feel both guilty and hurt, and i’m not really sure what to do. i love her very much and wouldn’t want to break up over something like this. it feels shallow. but at the same time, my needs aren’t being met. there have been times i asked if we could do it, and she said yes, but then later essentially revealed that she didn’t really want to anyway, and wasn’t going to despite saying yes. i just wish she hadn’t lied about it. and i used to find her so attractive but everytime i think “wow she’s so hot” i get a sinking feeling in my stomach, knowing she never thinks the same about me. i used to take my shirt off before bed just to try to get some attention. but she never looked at me any way, and it’s hard not to take that personally.

tldr: my gf and i might have incompatible libidos, and i’m scared for what that means in the future. i worry there’s not much to be done about it besides either accepting it, or getting sick of putting up with it.
