Answer me this... What is your characters alignment?
Here are some guidelines.
First, remember that just like D&D alignments, these are broad and don't encompass everything there is. Also this does not necessarily mean sex folks, could be just romantically, you know?
Second, no shaming folks for picking any specific alignment,
Third, even if not sexual, make sure you double check you characters age, just in case.

In case this sort of language is new to you
Top = Focuses on what they want, and on others afterwards, generally has a way they like to do things,
Vers = Will focus on either depeding on mood, Has preferences but will accept changes depending on the situation.
Bottom = Focuses on pleasing others, has no prefered way of doing things.
Dominant = Will take charge of situations, Will boss people around.
Switch = Can take charge, but is confortable letting others controls situations for them too.
Sub = Prefers that someone else take charge of things. Likes to receive orders.
Feel free to discourse on why you chose these, and exposit about your characters. ^^
Maybe link a picture too.

My boys are

Vernon - Which in spite of how small and wholesome he is, is actually a submissive top. Often liking to sit back and relax, but having certain things he likes to do more than others.
Sadly Grey has no artwork I can show yet
Grey - The most dominant top a dominant top can be, grey takes to his emotional and sexual life the phylosophy he applies to his work... He has a particular set of skills he is so damn good with, you really don't want him to step out of his confort zone.

Azreth - Despite the dastardly grin, Azreth is very versatile... Normally he would fall in the dead center of the table being able to go anywhere as he is great at code switching, but since he mostly interacts with Vernon and Grey and they are both Tops, he often finds himself in the lower end of the table.
