I think there's an expectation that a fic labelled as slash (or femslash) will make the relationship explicit, even if there's no actual sex. Sounds like you were writing UST (?) and with that there's always the "if you're clueless you'll miss it" part.

Oh. That fic again. I've been aware of the fanwank about it but haven't paid much attention because I wouldn't read Rodney-fic if you paid me (well, maybe if you paid me *a lot*...) so have no opinion on the fic in question. But, yeah. Thanks!
