It's commonly joked that within the first few moments of seeing a woman, men are envisioning what it'd be like to have sex with her.
I have to confess that within the first few moments of seeing a man, I'm usually doing something similar. No, no, not that similar. I'm sizing him up, assessing whether or not I could take him. Is this normal? If not, what do guys think about first when they see other guys? How much social prestige he has? How wealthy he is? Not much of anything at all?
How about women when they see another woman? How pretty she is (without the gratuitous male imagery that accompanies it)? Her sense of style?
