Being ace & having a high libido

I'm sure there's been a ton of posts like this one, sorry, but I need to vent.

I'm fully asexual, not even demi, and I have such a high libido. I'm AFAB so it accentuates when I'm ovulating, and it's SOOO frustrating. Like, when I ovulate I think about sex all the time! I consider myself ace because I do not feel sexual attraction towards anyone IRL but I do feel attracted to fictional characters, so I'm constantly fantasizing about having sex with them. I masturbate a lot too. Again, it's frustrating! Whyyy do I have to be asexual AND have a high libido??? Ughhhhh
