The university-educated brunette longed to be as confident in bed as Sex And The City maneater Samantha.
So she set herself a 10-year challenge - to get a thousand notches on her bedpost.
I'm sure she oozes confidence now.
Last month she bedded her Mr 1,000th at a friend's party. "He was gorgeous, blond and fantastic in bed."
Now the challenge is over Christina does have regrets. "Good friends stuck by me but others accused me of being a slut. I took things too far. Now all I want to do is settle down. I just hope I haven't put men off."
Mr. 1001 is going to be one lucky bloke!
