Is there anything more thoroughly vanilla than “rape fantasies?”
No. There’s nothing more vanilla. Or, really, less kinky.
You’re not a “Dom” or a “Sub” just because you get off on fantasizing or roleplaying it. It’s as vanilla as “roleplaying” Ravel’s Bolero on motel satin sheets. It’s as “kinky” as a French maid costume. It’s as cis/het tapioca-bland vanilla as a Danielle Steele novel.
It’s not bad if you get off on it* mind you. Any more than if you get off on “naughty [xyz] girl” Halloween costumes, Ravel, satin sheets, or Danielle Steele. Nothing wrong with vanilla! But like those other things it’s still utterly vanilla.
And as a matter of fact yes, I’d stand by my assertion even if I switched to decaf.
[* Unnecessarily necessary note: If you can’t tell the difference between fantasy and consenting-adult roleplay from criminal assault then you’re a danger to yourself, your partners, your community, and society.]
