Day 10: What are your hard limits?Not many.
I've got loads and loads of things that don't turn me on, things I don't want to do right now, or things I don't want to do in certain ways, but as far as things that I categorically don't want to do at all, ever?
It mostly comes down to stuff I think is unethical. I'm not doing anything with animals or with people who don't or can't give informed consent. I'm not doing stuff with someone behind their (or my) partner's back. I'm not doing anything where real-life sexism/racism/etc. is part of the play. Basically, if I don't find something ethically acceptable outside of kink, I'm not going to make an exception for kink.
Other than that, there's not much I find "ethical but too icky to ever consider." I'm an almost-nurse and roadkill-pokingly unsqueamish, so things involving bodily fluids and functions fascinate me more than they disgust me. Permanent marking doesn't necessarily bother me either--I don't want obscenities tattooed on my face or anything like that, but the idea of picking up some incidental scars suits me fine.
Oh! Gunplay! Gunplay is a hard as hell limit, at least in any form that violates the "all guns are loaded, all guns are real, do not point a gun at anything you are not willing to destroy" rules. Although knifeplay is fine with me--I've had a genuinely sharp knife right up against my neck--so I'm not consistent or anything.
And of course there's a whole pile of things I won't do that don't come up very often in kink, so I'd feel silly enumerating them one-by-one. I mean, I won't eat a brick? If anyone ever asks me to erotically eat a brick, I will not do that.
Maybe the ultimate hard limit for me is emotional pain. I don't ever want play to hurt my heart. I don't want a scene to ever intentionally make me feel worthless or abandoned or repellent. I want my play to hurt, but I don't ever want it to truly hurt me.
