[Bandana]

Put yourself in chastity for a while. Let the dice decide the time
of your release.

Buy or make a chastity cage if you haven't got one already.
(Make a chastity cage out of an ordinary sieve, a belt, a padlock,
and connections back and front between the belt and the sieve.)

Lock yourself up, then go to a remote place and hide the key.

Here comes the fun part: Get home, roll two dice and let them
decide the time until the cage comes off; just multiply them to
get the number of days until you may go back and get the key!

ROLL!

Good luck, and don't forget to "excite" yourself a lot!
