Quite a while back,
This American Life did a pretty fascinating interview with a female-to-male transgender person (for whatever reason, people don't usually talk much about the female-to-male ones) about how he was adjusting to his new life as a man, and he kept talking about how weird the testosterone was making him feel, in both good and bad ways (especially his newfound desire to start checking people out).
