Self confessed sex addict reveals she used to be a man.

A woman who revealed she has slept with 1,000 men has made another startling confession - she used to be a man herself.

Crystal Warren admits that there could be 'a lot of angry men out there' after they learn her secret.

The 42-year-old appeared on This Morning earlier this week to discuss her sex addiction - prompting Eamonn Holmes to ask why she hadn't turned to prostitution.

But she chose not to reveal her true identity until now, though insists she wasn't 'trying to hide anything'.

Miss Warren was born Christopher Snowden and changed gender in 2005, she has admitted.

She told The Sun: 'I'm scared there will be a lot of angry men out there reading this but I have to tell the truth.

'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.

'I don't want any man I've ever been with to doubt his sexuality now because of this. They didn't know they were sleeping with somebody like me.'
