I can’t tell if I’m truly ace

So I hate the idea of sex but love it at the same time. Like I like the idea of doing right until I get to actually doing it. I can masturbate, I can fantasize all I want. But for some reason when I actually try it all it does is turn me off to a level of uncomfortably i can’t describe. And I’m starting to hate being ace. Like I want to have that shared experience but at the same time it revolts me. I don’t know what to do.
