"to find myslef a man !"

What would the perfect man be ? He would be your partner in life, someone you can trust a 100%, who would always have your best interests in mind. Your perfect man would be straightforward, brilliant, eloquent, knowledgeable and wonderfully talented in everything. You would want an "alpha" type of personality, who wouldn't let people control or manipulate him, somewhat dominant, but in a protective way.
On another note, you would want him to have really high libido, an inhuman stamina, and to be, at least, a bit of pervert. In other words, to be like you when it comes to sexuality.

As for the appearance, you liked muscled tall guys and everything that looked masculine, broad shoulders, narrow hips, chiseled jawline, etc...

Now, such a man probably doesn't even exist outside of your fantasies but, you just obtained a power that can make those very fantasies real, the question now would be : how do you do that ? Do you transform someone into that man ? Probably the fastest way of doing so. Who to start from, then ? "Any guy would do, as I can pretty much change everything, even a girl could be changed into a man, for that matter", that would be the pragmatical answer but somehow, you didn't want anyone to become your ideal mate.

You reflected upon those considerations... The chosen person will most likely live a happy life with you, very long hopefully, it might be even for all eternity. It seemed more like a gift than a curse, it would be a curse if happiness was not guaranteed but you were precisely guaranteeing it.
Alright, decided : it will have to be someone who deserves such a gift.

Who do you have in your life that was deserving of that ? Someone who was always good to you ?
