Could this be linked into female phero levels as hhh probably is expecting i mean with the reward centres the beatiful faces probably are beautiful based on previous sexual behaviour \"eye is in the eye of the beholder or is that beauty\" anyway also linked to pheromone previously encountered.
Another side issue is that us males also go in so far as brain sexual functioning a high propotion of body you know breasts ass legs arms etc.
Also social status and fashion seem to play a role to a degree as well, so its a mixed bag really folks just my two cents worth.
Also bring into this the two types of males - the widespread type and the concentrate on one women type also plays a role.
Refer to the book sperm wars for more info and maybe the venus mars books.
