So, she's a wh*re?
thought, it was bad taste that she started to like the australian guy, but the next couple of days she has sex with the ex..then its just like,oh i cannot decide..
thought it was kind of predictable
The whole movie is "been there, done that" as far as I can tell. So yes, what you're describing would be part of that overused theme. And unless they paid her for the sex, she's a slut, not a whore.
But...If it were reversed: A man had sex with an Australian gal, but a couple of days later had sex with an ex girlfriend, leading to "Oh now what do I do?" or whatever, then what would you call him? I'm guessing "stud" or some other complimentary term. In fact, I bet it would go something like this: "He's the man! Why should he choose? He can just keep juggling them both as long as possible." Is the old double standard still alive and very well? Many sexual partners for a man = He's awesome; ditto for a woman = She's a most-insulting-term-possible.
Yes or no?
