Demi Moore is planning to gamble sexual favors with Ashton Kutcher in a bid to get pregnant.The 'Charlie's Angels: Full Throttle' star is keen to have a baby with her new husband, so the couple divide their time between trying to conceive and playing dominoes. Demi told Access Hollywood: "We're both addicted to Mexican train dominoes."It goes up to double 12's instead of double six and it takes about three hours to play."I'm not joking when I say we're addicted like two to three times a week."Maybe we should have some side bets just to you know, encourage side bets of sexual favors."The 44-year-old - who has three daughters, Rumer, 18, Scout, 15, and 13-year-old Tallulah, with ex-husband Bruce Willis - believes becoming a mother is the most empowering thing a woman can do. She said: "I think it is by far one of the most empowering experiences a woman can have."I didn't have an epidural, I did nothing. I did all of mine naturally and I left in two to three hours. I don't think doing it without drugs is for everybody so no pressure there."Demi also admitted she and Ashton, 29, would like to have a son. She said: "I wouldn't mind a boy. I wouldn't mind a little balance, you know balancing out that oestrogen."
