I didn't understand it either, Gwen
I am comfortable talking about BDSM to total strangers as long as they approach the subject first even if they are adverse to it.
I would never approach a stanger on a bus and bring up the subject.
I will bring up the subject if I am around friends or in a BDSM environment such as a club.

PS: My wife and I visited your website. We really enjoyed the art and poetry
