I'm confused on my sexuality

(CW: Masturbation). So I'm confused about my sexuality. I'm not into people irl in sexual ways, I mean I'd do it but I'm not into it. But what really gets me off is pretending to be other people. Whenever I masturbate I always pretend to be someone else instead of myself. Like I'd pretend to be a celebrity or a character, or just a "default person" but never myself. I'm confused cause I'm not seeing anything about this in my research.
