On Monday, I discussed the male half of the opposite-sex-friend (OSF) equation. Namely, while sex isn't the top priority for men forging friendships with women, it's still on their minds especially when both parties are single. That same OSF study I referenced asserts that women derive a particular benefit from platonic guy pals as well.
Last week on Stuff Mom Never Told You, Molly and I discussed the plot-driving question of When Harry Met Sally: can men and women really be friends? Of course, we'd all like to think that the answer is clearly yes, but when we started researching the topic, anecdotal and empirical evidence always circled back around to sex (this also assuming a friendship between heterosexual men and women). While opposite sex friendships (OSFs) are common and possible, sexual attraction tends to muddy the waters at some point.
