Crystal Warren, a retail manager from Brighton puts her sex addiction down to witnessing the painful breakdown of her parents marriage when she was five-years-old.
At the weekend she says she often leaves the house in the middle of the day to find men at pubs or coffee shops to pick up and take home.
On a bad day she has admitted to having sex with seven different men in 24 hours, sometimes a few at a time.
'I?d begin to feel hungry for sex,' she says. 'I?d go on the prowl for men on my lunch breaks. If I didn?t manage to have sex I?d be unproductive all afternoon. If I go without for a few days I start to feel desperately low, depressed and lack energy
She says: 'I know I?m a sex addict, but I can?t face getting professional help. Sex is the only thing that makes me feel good about myself. I guess when the men start saying no, I?ll stop having sex. I know some people must think I?m a terrible person, but believe me I?m not proud of myself.'
