No

You have no secret cock just a urethra and very large clitoris that extends about 2 inches out of your pink human vulva. You know that it is larger than normal because you remember when your sister fist measured your body to adapt clothing to fit your wings and tail. Even back then it stook out and your sister showed you her vulva to show you that hers tucked in neatly under a hood of flesh. With only a sample size of two and innocent as you both were at the time; you both went down bottom naked to ask your mum who was the odd one.

Being a dragon, who was naked all the time, Perscitia did not see the problem with her daughter and human treasure being mostly naked and asking about genitalia so none of you were embarrassed to talk about it and show off to each other. your mother's dragon vulva was blue and ringed by scales with a large scale that could seal over it when not in use, your mother only had one hole for all waste and reproduction. She had modified it temporarily for the king using magic but in both cases just above the large consignment scale was a small nub that would give great pleasure. The data lead to you being the abnormal one but your mother's love of maths reminded her that 3 data points were inefficient for an average.

This is where the embarring part came in. Your mother stopped some of the women who dropped off new food, clothing and other supplies for your half-sister. After making them swear that they would not reveal your existence to the king; or she would hunt them down and eat them; she got them to strip and compare their clits to yours. Their uncomfortableness at this revealed that this sort of thing was not normal for humans and really embarrassing which return embraced you. However, you got your data and concluded yours was indeed very large and abnormal. Which was even more embarrassing

Now that your gender is covered and you flashed back to a really embarrassing time what do you do?

You are standing just outside the castle you have lived in your whole life with your mother and half-sister behind the walls, clad in miss matched adapted armour and with a sword, shield and spear.
