I'm 19 amd gain nothing from masturbation

Ive tried to masturbate pretty much since I knew what it was, but I never get 'turned on' i dont even know what that means tbh. I also don't really get attracted to people either. Ive tried various ways of masturbation; hands, toys etc. But nothing really works. I don't even particularly like sex. I definitrly don't get off on it. I just have no libido whatsoever but I want to have a libido and to enjoy sex, although I never have...whats wrong with me?
