Unfortunately, there are plenty of "embarrassing" effects from ADT. What bugs me is my continuously shrinking junk. I do like the free manscaping though.
I too have experienced the mysterious shrinking junk. It's been four years since starting Lupron and just within the past few months my penis has begun to retract like an "innie", and looks like I was not circumcised. The pad tends to push it in even more. I know I lost a couple inches of length from the RP, but that was a long time ago. I'm sure my Uro will have nothing to offer to help (he never does).
But I have begun to grow a few dark hairs on my chest. Still fine and wispy though.
