in fact if someone is living in the wrong body you refer to that person in a way that person thinks he/she is like.

so if someone thinks he's a she you refer to him as a woman and vice versa.

psychologically funny is that: if you were to have sex with a person having boops and a penis but that person thinks or desires to be a woman, than that sexual intercourse would be considered heterosexual since there is a man and woman on spot.

in real life what heterosexuals/gays call a man with boobs and a dick I do not know.
