I actually really liked 'YPF' and despite its title, I'm sure it would've been more mainstream. Though, not perfect, it was somewhat original in its story telling of 5 couples and the different degrees/steps of making love (to put it nicely.) A lot of the stories were hilarious and I especially liked the married couple and definitely the kinky roommate threesome. The other three were interesting enough, and I did like the outcome of the Eric Bana-type's fate, but I liked it most when it strolled back to the married couple's discovery of boredom and how to overcome and a jerky roommate's desire to please his girlfriend while watching his very well endowed roommate bed her. In one night, in one "could happen anywhere" city, the story jumps between different scenarios while labeling the basic levels of sexual activity. The five are: a playboy and the new office girl, ex's reconnecting, a drained married couple, two roommates and a girl and, finally, best friends trying to take it to the next level. The movie is filled with complete eye candy, for both males and females. I should say, more accurately, all the females are stunning and as for the males, they really show diversity: from geeks to studs. While it only revolves around Caucasians, and homosexuals are left out, there's a little bit for everyone. And I say homosexuals are left out, as in no one's gay, but the roommate situation borderlines it. That is probably why I liked that story the best as they didn't just throw in the token gay couple, but they put people very open and not afraid of what society says they should be. Some of the writing and acting seems forced, for the most part it was entertaining, surprising and downright hilarious at times.
