I've read one definition of slash that it's "straight men having sex", which is fair in lots of cases. And it's possibly understandable when it is 99.9% women writing slash. But nowadays there's more available to read, watch, study about the way men relate to each other in situations that women wouldn't perviously have known anything about. So there's no reason not to get some realism into it.

And it's great when you run across an actual gay guy who writes slash fic! If they are a good writer it's like striking gold. There's a guy who writes slash for Bashir/Garak from Star Trek: Deep Space Nine (one of my favourite slash couples) and finding that was a joy.

Sometimes the slash story seems far too much like the standard romantic "bodice ripper" story, with the strong man and swooning heroine. But that means one of the guys has to be turned into the swooning heroine.

Luckily for me, I never read romance novels. :D
