1) too much porn glorifies it and make it seem as if it is not a real thing (excusing it as BDSM, which is NOT).
2) you don't really want to get r*ped. There is a "power play" fetish where - in a consensual and safe environment with safe words and aftercare - you get laid mimicking an abuse scene. Beware of not distorting what you read in fiction.
In your fantasy you are still in control, it's not an uncommon fantasy. Doesn't mean you really want an experience like that.
Sexual fantasies can be pretty weird but it's just your imagination. So there isn't really a need to change that. Most probably your fantasies will change over time. So don't worry about it
Why do i keep getting turned on when i imagine myself getting raped? No seriously i wanna stop this somehow
