It’s actually not that unusual at all for people to fantasize about what is called “consensual non-consent”.
If you get on certain sites that focus on alternative lifestyle, especially the BDSM sites, it’s a very normal sexual kink in those circles.
The important thing is, if you find a partner willing to explore such kinks, to establish safe words.
A common joke is, “Welcome to BDSM, where no means yes and pineapple means no.” 😀
