No, seriously, so many posts that completely missed Stuart's point.
Glad to see someone has got it at last!
There was a move away from compartment stock to open saloons (talking about day stock here) for personal safety reasons: it was all too easy to find oneself in a compartment (designed for six, but often not occupied to capacity) with someone unsuitable and a closed door between yourself and the rest of the world. It's time a similar move was made with sleeper stock (the existing stock being prety much life-expired, despite the so-called refurbishment a couple of years ago, where they didn't even change the carpets). Either a move to single-class sleeping accomodation with single berths - perhaps supplemented by more seated accomodation - and/or a move in standard class to either "capsule" style accomodation or cabins with larger numbers of people where there is, as others have pointed out, safety in numbers.
Gender/orientation is only one of a number of variables - what about age, sobriety, propensity to snore, recent consumption of spicy curry, chronic insomnia? - that go into determining suitable pairings. In fact, the more you think about it, gender may become the least of your worries. A one-on-one sharing system based purely on gender just doesn't cut it in the 2000s.
