i possibly should have put human, but since my main fandom often changes after a period of time, i didn't really know.

You can be human if your fandom changes; you only have to have one fandom at a time. (With, you know. Your girls on the side.)

plus, i cannot resist a good rodney mckay, but who can?

Not me, that's for sure. Oh, Rodney.

but do you ever really stop loving a fandom?

Well, I don't, but some people do, believe it or not. Yeah, I can't resist going back, either; my whole recs system is designed to let me revisit old fandoms.
