Every single emotion, thought, whim, impulse, feeling and etc comes from the brain.The more I think about this topic, the more I find that it is not true. How about the people who got castrated? I got a feeling that sex comes MORE from "down there" (sex organ) instead of 100% "up there" (brain)
All the flippin time. Especially while raping people.
I don't keep track about how much I think about sex! =P
