She is a he.

In real life, Tina is Tinari Le'Fae. He was born smaller than anyone else in his family, and growing up he looked more feminine than masculine. Secretly whenever his family was away, he would dress up in his sister's outfits and pretend he was born a girl.

In EVO, he decided to create the person he had always dreamed of being. Long hair, a cute body no one could confuse for a male, even petite breasts. But even with all this, he left one thing, his dick.

Although dick is the wrong term for what he had. It was more of a little clit, being only two inches hard. Tina loved being humiliated about his "clit", and decided to bring that into the game with him.
