Femboy Concubine

You made first contact with the Japanese in 1543 when you and your men landed on Tanegashima Island at the southern tip of the Japanese Archipelago after your boat was blown off course. When the natives found you they arrested you and since you looked so exotic and had such exotic goods they shipped you straight to the Shogun. You arrived at the capital as a prisoner but became good friends with Shogun Tokugawa Ieyasu and he agreed to give you a ship if you'll set up a trade agreement for him when you get back to Portugal. Once you're set free and allowed to roam the palace as you please you start to learn as much as you can about the people that live here. That night at the palace feast you impress the Shogun with your newfound understanding and respect of his people so much that he says he'll give you a Concubine. As you get back to your room you see that the walls and door are made of decorated paper like the rest of the interior so far but you can see the silhouette of a figure lying on your bed waiting for you in your room. You assume it's the Concubine and when you slide the door open you're greeted by a gorgeous young man in a kimono spread out playfully on the shikibuton. I was the first to volunteer to be your gift. He says in a flirtatious and eager manner My name is Minamoto. What is your name, European?
