She was born in Uruapan, Mexico on July 26, 1973. Her family migrated to Sunnyvale, northern California when she was seven years old. Vaniity comes from a large family; she has six brothers and four sisters. She is of Purepecha descent. According to Vaniity, she lived as a feminine boy who subconsciously knew she would grow up to be a girl; "I dreamed of being a wonder woman of sorts, I have always admired strong women, especially brunette women, I secretly wore my sisters' dresses, openly played with Barbies, played makeup artist and fashion consultant to my mother and sister."
She is currently a pre-op trans woman and does not plan to have sex reassignment surgery. Her main reason for the decision is the fear that she will lose genital sensitivity and never have an orgasm ever again.
