Dead libido

I have no sex desire and it’s ruining my relationship. There are periods of time when I want it multiple times a day, and then there are periods like I’m in now where even kissing grosses me out. I hate using the word disgust but that’s honestly what it is. The thought of saliva or fluid grosses me out. And I won’t say it’s my partner, I imagine having sex with other people, genders, or even solo sex- masturbation. And all of it is repulsive to me. I don’t know how to get out of it.
