Well, I almost didn't reply for fear of the kind of retaliation you inferred in the OP.
I am a guy who craves a session with a domme who will completely take over the session with bondage, cbt, tit torture, strapons and the like. I'm not much into spanking, but wouldn't object to a little lite spanking. In other words, want to be completely at the domme's mercy. With 2 exceptions: I want to choose the lady, and I want the session to end in a GFE experience.
I have had 2-3 sessions like this. The first one I reviewed. The lady sent me an email saying she was stunned that I did so--most men wouldn't review a D/s session. The other 2 I did not review.
The people on this board are pretty open-minded, but I think they do draw some lines. I'm not sure what some of those lines are which probably results in being reluctant to post reviews of these kinds of sessions.
If I remember correctly, on the mother ship there was a forum for these kinds of reviews as well as ad space. So if you were interested in this kind of conduct, you had a place to go to narrow your search.
Most ladies, in their ECCIE Showcase, just put GFE, PSE or Fetish for the kinds of activities they consider. If she wants, a lady can be more specific on P411, but not all ladies are that specific.
I think a lot of ladies who are willing to engage in the D/s conduct in the P4P world don't say so. Their fear is the same as mine. The fear of being "banned" (unofficially) by some members in the hobby.
In the final analysis, I think that we say we are open-minded, but we really aren't. This community still has bias against certain kinds of conduct. Taboos, so to speak. The kind of conduct in which I like too engage may not be embraced by all people, but it should be OK to all people as conduct occurring between consenting adults.
