Twenty-year-old Mark is the Bill Henrickson of a polyamorous compound of inflatable pool toys. One of them, Leila the Dragon is "like a wife" to him, with some of the sweetest eyes and smile that, quite frankly, Mark has ever seen. Like his fellow looner, Dave who was profiled last year on Nat Geo's Taboo, Mark keeps a pure, non-sexual relationship with the inanimate objects he loves.
