I dunno, I would say that's more of an opinion than anything else.
Well, her being 'family minded' isn't. That one's a quote.
There's nothing wrong with the thought of Tifa being a more open and sexual person in general than she was with Cloud; hell, I've always thought she was so shy with Cloud because he was one of the last connections to her broken past.
Still, there's a difference between being 'open and a sexual person' and having sex with people casually. And no, there isn't anything wrong with it. It just seems at odds with Tifa's overall portrayal. I'd also say it's at odds with Yuffie's portrayal, Red's portayal, Vinnie's portrayal and even Cid's portrayal to some extent. Kinda in line with Zack and Aerith. Probably most of the turks.
Irvine, Zidane, Oddly Shantotto, all those come to mind as always being in that sort of vein.
Addendum: Palom. Palom I can DEFINITELY see doing this.
Zee wasn't being very serious when she said that, she was poking fun at how much everyone was bitching about Tifa's sexuality moreso than anything else.
But no one was 'bitching.' And she did a very poor job of communicating that she was being facetious.
i'm not functional enough for human relationships
Does this hold true for everyone else, or is this a private pity party?
