[30M] I can’t stay physically interested in a guy and I worry about my ability to be in a relationship.

I can eat the same food every day for years. I play the same game, on the same character, doing pretty the same thing for 7 years off and on now. I listen to the same songs over and over. When I go to a restaurant, I choose one thing and order it every single time.

But with guys? I lose interest after one hook-up. Sometimes I lose interest before we’ve even met. I can’t even watch the same porn video more than once, it just won’t do it for me. I’ll see someone super super cute but in real time I can feel their shine fading. I’m 30 and I’ve never been in a real relationship (I dated someone for ~4 months when I was 22 in college but I don’t think we were into each other, we just wanted to be in a relationship regardless of with whom).

I don’t really enjoy sex. I get horny and turned on, and I like the idea of sex, but I lose interest very fast especially once the clothes come off.

Does anyone have any experience with something similar?
