A MILLIONAIRE who had a sex-swap operation to become a woman wants to be a man again. Dad-of-two Charles Kane became Samantha seven years ago. He claims he was rushed into the decision and is now suing his surgeon for £186,442. Property developer and designer Kane, 44, says he agreed to the op after his wife left him and he suffered a nervous breakdown. He claims gender identity specialist Dr Russell Reid convinced him to have the sex-change surgery.
