I've had sex in cars and outside plenty of times, lol
*However* my "magnum opus" of a place, I guess I could say, was when Synthetik and I had sex at an old civil war fort (turned state park/historical site),
Fort Macon. We had a sort of "date day" and went there and there really wasn't anyone else around. We went into one of the rooms that was semi-underground and I had written on me in marker, "Synthetik's Slut", which I showed to him while we were in there, and thus the public sex ensued, lol. I'm surprised I stayed so quiet, because usually I'm really loud during sex (I'm lucky I was able to, though, since the fort's rooms tend to echo). (Here's my
blog post about it, so that this doesn't turn into a text wall, lol)
But yeah, that's probably the coolest public place we've ever had sex, lol
