Well, he's theories weren't really about sex, but if it weren't for him, we'd all blush here at the mere mentioning of the s word. He just basically said, that the urge is the main force that keeps you going (just look at the people - it's true for at least 80% of them), so you should not repres this feeling (like they did prior to his findings). So in fact he started a sexual revolution by saying that it's O.K. to have sexual urges. But later on he was too sure of this theory and excluded all other options, which was his biggest mistake.
So, have any more cool drawings?
I especially liked the reference to communism in the first one, the sickle looking like a part of a machinery.
