The current motivations are mostly libido elimination, so I do not necessarily consider sex drive to be "the good stuff." Before surgery I thought it might be interesting to be without libido, and I may have even sexualized the thought, but it was not really the main goal. Now that I have experienced life without libido and then went back to having it again, I realize that I much prefer being without. Although I do suspect that mrt's suggestion about it being like puberty again could play a role in my discomfort. But there are other reasons as well.
I've thought about DHEA, but now that they want to make it a controlled substance, not so sure it would be a good idea. If you want to bring it with you though, I don't see any harm in giving it a try
A neutralizing hormone - something many of us at the EA have wanted for a long time. You'd get all the benefits of hormones without any masculinization or feminization.
