I think, obviously, that it's largely a matter of the spectator's (or participants) individual taste.

There are certain things that I have no interest in watching or doing (scat, blood, pain beyond the enjoyment of the recipient), and certain things which I love that others may have no interest in (public humiliation, watersports).

I guess the crowd that watched your scenes that night was kind of "middle of the road". And if you get 100 responses to this thread, you'll probably get 90 different answers.
