Feminine 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 more common feminine form; her lovely body is outwardly female but under her clothing lies a penis as well as a vagina.
You haven't had a chance to play with her gender before now and you can't wait to get to know her... intimately.
Sadly, you haven't yet had a chance to do much more than imprison her, 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' her?
