If you were born a man, and you transition into a woman and start dating women...are you a lesbian or straight?

Lol...it sounds complicated but it's a straight forward question. So popular transgender Sydney Starr was born a man. He turned into a woman and dated a few z-list male celebs. 

Now she says she's a lesbian because she may be having an affair with 90's actress Cherie Johnson, from the 1990s hit show Family Matters. She played best friend Maxine “Max” Johnson. So, does dating a woman now make her lesbian when she was actually born a man? Please answer...your time starts now! Lol
