Let's hear you! I will start. The strangest place I ever did it was also one of the biggest turn ons for me. I did it in the back of a Volkswagon Beetle. One of the old ones made in the 70s!
It was cramped for sure but I don't remember it being a problem for us at all and it was downtown on a side-street around sunset time, so there was just enough twilight to give us some cover but still some people walking by saw us.
