Sex dice is a dice game intended to heighten the sexual atmosphere and promote foreplay.[1] Instead of numbers, each face on the dice contains the name of a body part; the body part that faces up when the die is rolled must then be given sexual attention.[2] The Daily Princetonian suggests rolling sex dice to "break the ice and extend [one's] foreplay."[3] The University Daily Kansan advises a roll of the sex dice for those who are not particularly limber (and therefore cannot try "new and inventive position[s]") as a means to "bring variety to [one's] bedroom romps."[4]
A commercially available version, also called Foreplay Dice, consists of two dice, one with body parts and the other with activities; a roll of the dice will determine which action is to be applied to which body part. According to a 1999 SPIN magazine article, the game was especially popular among American teenagers.[5]
