I don't think it's because men are in gay marriages or civil partnerships because that actually affects a tiny number of gay men. For example in 2009 there were just 6,281 new same sex civil partnerships in the UK and 351 dissolutions (population 60 million). I'm certain there will be even fewer marriages because of the religious connection. But I think it's true that for a while now we've been heading in a more puritanical direction.

The other day I read that young people don't care about "brands" so much anymore. So maybe they're seeking out the amateur stuff. Swapping their own even... I find a lot of commercial gay porn unappealing these days. Formulaic and cynical, with ugly guys, and I know that in many cases there isn't the budget to do anything better.
