For those of you who are not members of the human race, a few reasons why Anthony Weiner might initiate cybersex conversations with attractive women over Twitter:

1) He’s a middle-aged guy with attractive young women willing to throw themselves at him from afar.

2) He’s cut. Above the waist, anyway. Probably below, if he’s Jewish.

3) He’s a middle-aged guy with attractive young women willing to throw themselves at him.

This doesn’t change, of course, that such behavior is risky, stupid, and apparently threatening to both his career and marriage. This is self-evident. But it’s also self-evident why a popular public figure might have a prurient interest in some of the people who are attracted to his public image. Can we please stop with the “why would anyone step outside the narrow bonds of monogamy” brow-beating?
