You know, there were a couple interesting LJ articles on slash I ran across a while ago, and I wish I had bookmarked them, but what this author was theorizing is that, the reason so many women (and particularly heterosexual women) like slash is that, well, there are men in slash. And she went on to do this whole study on het, lesbian, and gay porn, and then het, lesbian, and gay romance fiction.

I could ramble out more details if you're interested, but I didn't want to drop a big ol' block of text all at once. XD
