Teamwork

According to the LDS Church, masturbation is a sin. They even have a website offering useful suggestions for overcoming (no pun intended) your addiction.
My favorite suggestion is to shout out the word "Stop" if you begin to feel the urge.
If that doesn't work, you may want to get out of bed and make yourself a snack, even if you're not hungry.
You should always wear thick pajamas, these provide an extra barrier between you and the sinful area.
Of course, you must immediately cut all ties with any friend or acquaintance that continues to participate in this behavior, however,
try not to spend any time alone. Hmmmm....
Don't admire yourself in the mirror when coming (sorry, I did it again) out of the shower, quickly walk past the mirror to put on your briefs. (Are all Mormons aroused by the sight of their own genitalia?)
If all else fails, do the obvious, pray... or just put a Bible, instead of a dick, in your hand.
My friend Matt suggests wrapping your penis in duct tape.
If you have a slip and your hand heads south, just put a dollar in a jar every time it happens and give this money to your Church on Sunday.
My co-workers and I have started our own collection.
Although we're not giving our money to a church.
We're buying a new plasma TV for our office.
We should have enough money by Friday.
