Perhaps surprisingly, the momentary pain of being teased can lead to pleasure. During their 15 seconds of humiliation, the targets of teasing displayed common signs of embarrassment — gaze aversion; a coy, nervous smile; a hand touching the face; a head bowed submissively so as to expose the neck; and blushing. These gestures are ancient signs of appeasement that trigger a reconciliation response in most mammals, as they did in our study. The more targets showed these evanescent signs of embarrassment, the more the teasers liked them.-NYT Times article, In Defense of Teasing (page 3)
This probably explains why I'm so endearing.
