Well, I once had sex, me on top of him, penis/vagina intercourse, in Harvard Square, about a block from Harvard University in broad daylight on a weekday afternoon. I think that's THE MOST public sex I ever did. Thinking back to how much public sex I had with that guy, it's a wonder we never got arrested! I *was* wearing a long, full skirt and no panties, so we were not "indecently exposed". <Laugh>
