I have done it a number of times in airplane restrooms.

I ones had a hand job by a girl I just met on the flight somewhere over the Atlantic back in the seventies. Does that count?

But the weirdest place was in a stall at the men's room at the American Airlines maintenance hanger at SFO airport back when I was doing a college summer job washing airplanes... You know young and popping a woody that would not quit without some attention. That should be up there on the list, not quite in the vatican but up on the list non the less.
