Ooooh, mean question. Bad poll, bad!
Being the voyeur.... watching someone strip, wank, fuck... lovely! Turns ya on and gets ya going. Another volume in the library of "things I can wank to" that are stored in my head.
Being the exhibit.... knowing that someone else is getting off on seeing your body, seeing you have one off the wrist or getting jiggy with it... makes me even more horny and turns me into a soggy mess.
Now, being swingers, my hubby & me have been known to indulge in both, in fact either of the above options tends to lead us into joining in or calling over the 'watcher'.
Greedy? Moi?
Damn right!!
