I’m straight but find milking videos and the idea of being milked hot. Any clue why?

No attraction to guys but I find milking videos and the idea of being milked hot to think about. Maybe it will sound narcissistic because I’m fit and hung, so idk if it’s an attention thing or because your dick is like the star of the show or how much the guys like pay attention to it in the videos, but as a normally dominant straight guy the thought of being used like that or the power dynamic is hot to think about. Any thoughts?
