Eventually, we moved to the largest room: wall-to-wall mattresses. It was well-populated with couples, some of whom were vigorously enjoying each other's company. I felt a little shy as I leaned against the wainscotting. These couples were not the kind you saw in mainstream porn: They were all sizes, all ages, and all hair levels. They were enthusiastic and exuberant. One woman unwrapped her legs from one partner, who wandered, naked, out the door in search of the bathroom, and motioned another man towards her, giggling. There was a lot of giggling, actually. People were definitely having sex, and they were definitely enjoying themselves. That alone was pretty fun, so we started kissing, which led to some groping, which led to a strategic retreat to one of the mattresses (after first carefully laying down a provided towel). By the end of the evening, all of our shyness had disappeared.
