Hot Or Not

According to Seed Magazine, a recent brain study revealed that the subjects' brains reacted to erotic images 20% faster than all other pictures, before the subjects were even aware that they were looking at an erotic image. The initial study examined women only, but when men were tested, they were found to react at the same speed as the female subjects, contrary to some commonly held ideas about sex drive.

Of course, when they tested gay men, the reaction was 200% faster. Even faster, if they were on Manhunt.
