Masculine Hermaphrodite

Your kind are well known for having four possible genders, a hiccup of genetics that formed so many millennia ago that no knowledge exists of its origin or reason. There are the standard male and female and then there are the two forms of hermaphrodite, masculine and feminine.
Lovely Doe is the rarer masculine form; he bears all the outward features of an extremely pretty male but under his clothes he has a vagina as well as a penis.
You haven't had a chance to play with his gender before now and you can't wait to get to know him... intimately.
Sadly, you haven't yet had a chance to do much more than imprison him, due to the hectic nature of war. But now it is over and you are free from obligations for a while.

How exactly did you 'acquire' him?
