Scat, eh, not my thing but I don’t find it repulsive. Not being grossed out by shit makes enemas more convenient. Watersports, sure, I’ve had a dom use me as a urinal, pretty hot. Rape? Sure, on the receiving end. Mostly in the vein of CNC with bdsm.
Yeah, I’m not a huge pain person either. I don’t enjoy the pain, I enjoy the submission, if that makes sense. The dom I occasionally see will alternate between spanking me and gently stroking my body, building the anticipation and juxtaposing the pain, and will fake on spanks–it’s truly something I never thought I’d love so much.
