I wouldn't say I'm "familiar" with the homosexual lifestyle, but there's something that tells me that a penis does not belong in a pile of feces. And jumping from hot tub to hot tub to make that happen as often as possible cannot possibly be anything other than a mental disease. But hey, that's just the way I was raised.
It goes beyond the disgusting acts; the fact that so many of them feel the compulsion to engage in such behavior with total strangers (rest stops, bath-houses, etc.), and the number of such encounters, is absolutely bizarre (they were sitting ducks for the likes of Jeffrey Dahmer).
