I can't, of course, but if I were single, I would. The Dom would have to be very clear and precise about what he was looking for though, and I would want a lot of information. I have read only two personals here on the forum that intrigued me. I would have contacted either of those doms, if I had been single. ( I read the personals out of curiosity only.)
I have been in chat channels and been contacted by "Doms" looking for a sub, but most weren't real. They would try to get me to play on line even when I told them I was taken already. That's why I stopped visiting chat rooms. Thank goodness for this forum and library chat where that doesn't happen. I can talk comfortably in both places and the Doms/Dommes respect each other's property. A little harmless flirtation here and there is all I have ever seen.
