I have hinted/joked around with a few friends...mostly female friends about it. If I date anyone for any length of time I talk about it. I've had mostly good luck with g/f's getting into it to some degree. Spanking and other related activities are deal breakers for me. If a woman is grossed out by it or to conservative to do it etc... then there is no point in continuing a relationship with her.

I have no interest in "coming out" to my friends or family... the thought kind of repulses me.
