good question
and a great post by Scorpio!!

i think for the most part, i have to agree with what others have said. covert play is something that some may notice, the alert ones in any case - where exhibitionism is blatant.

i prefer covert play myself. the intrigue of wondering if we will be seen, or are we being watched is an incredible turn on for me. i suppose some exhibitionism has turned me on as well, such as sucking Master's cock infront of His friends. But then, maybe that doesn't fit the bill as they were well aware of it in advance...and looking forward to it too
