It's been a hell of a week for Crystal Warren. After going public with her sex addiction and revealing she slept with over 1,000 men, she faced a controversial line of questioning on British chat show This Morning and has now revealed to The Sun that she used to be a man herself. The 42-year-old, who was born Christopher Snowden, underwent full gender reassignment surgery in 2005 and was issued a Gender Recognition Certificate, which allowed her to legally change her birth certificate to reflect her new name and sex. Three years prior, she underwent counseling and begun having hormone and laser treatments to remove body hair and develop breasts. "A lot of people will think I've lied to those I've had sex with, but I don't feel I have because I'm a woman and my past is all behind me," she said. Warren said she has suffered from gender dysphoria—feeling as though she were a female trapped in a male's body—since childhood and that her parents were supportive of it even at a young age. She had previously revealed that her sex addiction was so consuming that it has left her unable to hold down employment, but that she's not ready to seek professional help for it.
