that's partly what my story was about, how the lines of fiction and reality are blurred, though I didn't see it as sordid, more as painful.

I didn't mean the idea of them having sex is sordid (though if it's adultry then I suppose by technical definition it's sordid). Your fic didn't strike me as sordid at all. It seemed quite respectful of them both. I meant having to question paternity and pretending it's not an issue is sordid.

I think in RL exclusive relationships, that kind of sordidness seems normal to me. It doesn't bother me because it's the kind of thing so many real people do. Where as with M & S I fully expect their relationship to be so much better than that.

YMMV.

Oh, definitely. Maybe even more so with RPF.
