From the Reddit discussion:

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. http://www.reddit.com/r/cogsci/comments/lipbp/testosterone_and_social_functioning/c2t254p

linking to http://tranifesto.com/2010/06/30/testosterone-and-sex-drive-my-second-adolescence/ - interesting indeed.
