Hollywood star Charlie Sheen, who is thought to be addicted to women, has revealed that the day he lost his virginity to a prostitute in Las Vegas was the ''greatest night'' of his life. The actor said, he was only 15 years old then and stole his dad's credit card to pay the flame-haired Candy. Sheen said that during the romantic act in a hotel room, his father Martin Sheen was sleeping in the room next door. Telling that he also gave an opportunity to his cousin to enjoy with the call girl, paying once again by his dads card, the former Two and a Half Men said, ''I told Joey, 'Look, this is my dad's credit card, you're going second. He was thrilled. He didn't give a s**t. I remember having the greatest night of my life.'' But two weeks later Charlie's father got to know about the transaction and the actor had to confess. The star said that his dads only concern was that he should not mistake his night of passion ''for love''. ''Then two weeks later, my father wanted to know about his Friendly Introductions LLC, Las Vegas, bill on his statement. I explained it. His whole concern was that I didn't mistake that for love. I'm still trying to process that one,'' the star said.
