One of my favorites cause no one likes a dumb ass person in their bed. It is a trivia game. In fact, you can play an actual game if you like such as Trivial Pursuit. Tell your partner that they have to get a certain amount of answers right or they won't get sex that night. You can even watch Jeopardy or Wheel of Fortune and play this or, if you have been with your partner a considerable amount of time, ask them questions about you that they should know the answer to. This game can be fun especially when your partner is badly wanting for some sex and you make them earn it.
