I go to kink clubs a lot (like, weekly at least 😈) though generally I don't fuck there, I just play BDSM. Not every time I go, but I often get offers. But my current girlfriend is a bit kinky, though she never goes to the clubs with me. It's not how I met her either. So putting a leash on is no big deal as I have all the kinky stuff and she knows I'm into it.

She doesn't like faceslapping me, in fact even many dommes don't. They find it too humiliating or are worried about causing damage. But it really turns me on so I often play with the ones that do.

I also go to kinky dance parties, often with a domme friend holding me on a leash.

If you have a partner, I would recommend just bringing it up, perhaps in a milder way at first, to see if she likes it. It was a barrier for me at first too but I feel very liberated since I opened up.
