Researchers once again discover the obvious:
Daily experience suggests that non-romantic friendships between males and females are not only possible, but common—men and women live, work, and play side-by-side, and generally seem to be able to avoid spontaneously sleeping together. However, the possibility remains that this apparently platonic coexistence is merely a façade, an elaborate dance covering up countless sexual impulses bubbling just beneath the surface.
New research suggests that there may be some truth to this possibility—that we may think we’re capable of being “just friends” with members of the opposite sex, but the opportunity (or perceived opportunity) for “romance” is often lurking just around the corner, waiting to pounce at the most inopportune moment.
I've had a number of female friends with whom no sex was involved, but that's certainly right about the impulses "bubbling just beneath the surface." Or, as Harry said, it's impossible for a man to be just friends with a woman he's attracted to, because he always wants to sleep with them. Well, what about the unattractive ones? "He pretty much wants to nail them, too."
