How open are you about your kinks?
This depends a lot on the kinks and their perceived level of deviance. There are certain things I will share freely and without hesitation.
I'm open to the fact that I enjoy giving women massages. I like cooking for them. I like pampering them. None of those are secrets to me. I don't care if they know that she wears the pants.
If someone asks, I don't hesitate to tell them I am on bottom in sex nor that I enjoy sexual bondage play. Most of these things are fairly normal activities for vanilla couples even.
The rest of it stays private.
