It reminds me of that article written by a female-to-male transsexual about the effects of introducing testosterone to his body. He specifically mentioned that most activities (especially sex) had become obscenely more focused on the goal or end-result, and how the rest of the journey didn’t matter so much. I can probably find it again if anyone’s interested.
