I'm no expert on fanfic, but I would imagine anyone writing smut using borrowed characters - whether those characters are m/m, m/f, f/f, or any other geometric combination - can be said to be making their own porn. Do you think m/m makes more of a statement than other kinds of erotic writing? Not criticizing, just curious.

I also read an article somewhere (link escapes me, unfortunately) that women enjoy writing m/m because from the outside a relationship between two men seems more egalitarian than anything they've read or experienced with m/f pairings.

I'd love to read why you love femme stuff! My own tastes run the gamut - I enjoy reading about just about any pairing or combination as long as it's well written and the characters are interesting enough to care about.
