In reguards to sexual side effects, I can only speak from my personal experience in that I found it to have both positive and negaitive effects. On the positive side, I found the additional aggression to put me more in a "menal" sexual mood, with feelings of a lot more mental sexual stimulation. The feeling of male dominance made me want to jump every cutie around, abeit more in a control/force way then an intimate/romantic way. On the negative side, I found it hard to maintain an erection towards the end of the cycle unless me and the little one were being quite rough. (Which is okay because we like things that way) If we went for a slow and easy evening, I would have a hard time getting/maintaining an erection.
Just my personal experience.
