Had sex on the beach in the Bahamas, at night and under a tree in a lawn chair. Pretty sure at least one other couple saw us.
Had sex while pressed up against the hotel room window...no idea if anyone saw us but we were in plain view.
Had sex (when I was much younger) in a public park.
Had sex (again, younger) on the hood of my parents car while it was parked in the driveway (and it was dusk...meaning we were visible).
Had sex in an elevator and also in a computer lab at school when at Ohio State.
<sigh> exhibitionist here.
Oh...almost forgot....almost got caught by a cop while giving a bj while parked on a side street in downtown Columbus. That was about 3 years ago.
In case anyone's curious...led a boring past 2 years. Looking for more exhibitionist ideas
