Also, I/we needn't have just one fundamental motivation. I would also kind of die if my sense of curiosity was taken away from me. That doesn't make me better or worse than uncurious people, just different.

Perhaps there's an evolutionary motive, a basic biological reason for it. I suppose an obsession with sex is not always in nature's interests.
