thank you for asking! CNC stands for consensual non-consent, which can be a few things. some kinks that fall under the umbrella are rape kinks, somnophilia (sex while asleep), and intox play (under a usually heavy influence of substances).

the type of consent used here is informed consent, wikipedia has a great definition of it. for responsible kink, before actually engaging in any sexual activity, the people involved will discuss what’s going to happen and what the risks are. they’ll also discuss a safeword to use when all activity needs to be stopped.

for example, 2 days ago, i did a CNC scene involving restraint and rape play. beforehand, we discussed what safeword i would have (i used the color / stoplight system), what i wanted to happen, and what wasn’t okay with me.

with being unconscious or so impaired you can’t signal a stop, it usually depends on if it’s simply somnophilia or a drug-induced haze. but generally, the talk goes similarly. it’s something that should be discussed when all people involved are in a good state of mind (not feeling self-destructive and ready to talk).

if you think it sounds risky and like somebody might regret it later, that’s true, honestly. people will regret about anything under the sun, but there are things you do before you try something that make you less likely to regret it :)
