Lady on the right is probably a "social butterfly" and not really self-conscious. Dude on the left is most likely self-conscious and self critical. Because of this, he may think he's ugly or whatever and doesn't create many chances with dem womenfolk for dating or just plain old sexy times. Also this is probably a question where you expect the majority of the answers to be "Oh, she's fat. She couldn't have ever done it with anyone."
