No.

Firstly kink isn't inherently sexual.

Secondly, I'm talking about things like 'subspace' and hypnosis (hypnokink) where there is little - no thought happening.

If you would like to know more there is an excellent asexual kink educator on youtube called Evie Lupine.

Also, there's a community on lemmy for learning about kink: !kink@lemmy.blahaj.zone

Hope this helps!
