Love and Sex (2000)

Beautiful young journalist Kate Welles is frustrated with the puff pieces her editor always assigns her. She is also deflated by being left on the doorstep of a lengthy live-in relationship with lover number thirteen, Adam. Fancying herself somewhat of an expert on the archetypal love/sex differentiation, she relishes an opportunity to write an article about the subject. But as her preparations lead her to reflect on some of her more ill-fated encounters (from the high-school Lolita-phile, Gerard, to the ardent but unexpectedly married Eric, to Adam, her beloved artiste terrible), Kate begins to question some of her choices and apparent inability to commit long-term.
