My character is 17 year old Korra, a gay kid who is only out to a few people. He is about 5'9, slender and attractive with one blue eye, one blue-gray eye and silvery blonde hair.
Korra is, to put it bluntly, a highly sexual virgin. He wants desperately to experience attraction, love and pleasure with another man.
He has met your character, and the friendship has turned into more. Your character is tall, classy and very handsome. He has no problem attracting both the sexes; he is either bi or gay. He sees Korra as an unexperienced, eager youth who's innocence is fragile and needs careful handing, even if the boy is hungry for him and horny as all hell.
Your character is a bit older and more calm, whereas Korra is eager and extremely attracted to your character in a less than controlled way.
