What is the current Church policy on masturbation?
The Church teaches that masturbation and pornography use are sins, but they are not serious enough to trigger a membership council. However, certain cases of pornography use may result in disciplinary actions.
Is masturbation a violation of the law of chastity?
Yes. The law of chastity, as taught by the Church, includes a prohibition against masturbation. Christ taught that whoever lusts after a woman "hath committed adultery with her already in his heart," and masturbation involves lust. Although Christ's language is geared towards men, the Church has made it clear that the law of chastity applies to both men and women.
Can you get a temple recommend if you masturbate?
It depends. Temple recommend questions—including "Do you strive for moral cleanliness in your thoughts and behavior?" and "Do you obey the law of chastity?"—give bishops an opportunity to counsel people struggling with masturbation. However, there are no specific guidelines on what would merit withholding a temple recommend in this context. This decision is left up to the discretion of the bishop. 
Does the Church have a policy about bishops asking about masturbation?
No. It's considered within the bishop's purview to ask about the law of chastity. This may include asking about masturbation.
Isn't it kind of creepy for a bishop to ask people if they masturbate?
Yes and no. If you see bishops as spiritual counselors, and the law of chastity as a spiritual law, then it may be awkward, but not necessarily creepy. But if you don't recognize the bishop or the law of chastity as valid, then yes, it may seem creepy to discuss your personal sexuality with him.
There have been cases when bishops have abused their roles and done creepy and/or illegal things. In these cases, they are subject to Church discipline and/or legal action.
Are you supposed to confess masturbation to bishops?
Possibly. Masturbation is not considered a serious sin, but it can be spiritually damaging, especially if coupled with pornography use. If masturbation is a problem that is impacting your personal well-being, your relationships with others, or your spirituality, then yes, you should probably talk to your bishop.
What if I'm a woman and I'm more comfortable talking to my Relief Society president?
Talking through things with other leaders can be helpful. Bishops often work closely with Relief Society presidents when counseling ward members on difficult issues.
As the local priesthood leader, the bishop holds keys to help with repentance and spiritual well-being, so it's important to meet with them as well. But it's also an accepted practice to request another adult be present in interviews, such as a Relief Society President.
Does the Church have a policy about masturbation and qualifying to serve a mission?
No, not specifically, but as of 2017, priesthood leaders will ask prospective missionaries about pornography use. Readiness to serve a mission is determined by the missionary, their bishop, and their stake president.
Does For the Strength of Youth specifically mention masturbation?
Yes and no. The word "masturbation" doesn't specifically appear. Instead, it says, "Do not do anything . . . that arouses sexual feelings. Do not arouse those emotions in your own body."
Is the word "masturbation" specifically mentioned in any Church handbook?
Did the Church ever teach that masturbation caused homosexuality?
No, but sort of yes. Masturbation causing homosexuality was not doctrinal or generally taught in the Church, but there are two sources that discuss it.
In 1969, Spencer W. Kimball said that masturbation could lead to mutual masturbation, which could then lead to homosexuality. Also, a 1981 internal publication for bishops stated that early-life masturbation could reinforce homosexual interests.
Why would the Church leaders think masturbation causes homosexuality?
If they did, it was probably because, based on the collective experience of Church leadership counseling with homosexual members of the Church, they perceived that there was a correlation between masturbation, mutual masturbation, and homosexuality.
Why do some therapists, even Latter-day Saint therapists, teach that masturbation is okay?
Probably because Latter-day Saint therapists have a variety of religious and philosophical approaches to their practices. Some of these practices are in harmony with the gospel, and others, less so. Mainstream psychology treats masturbation as acceptable human behavior. Some Latter-day Saint therapists may subscribe to this view.
Some faithful Latter-day Saint therapists have used masturbation as a therapeutic approach to sexual dysfunction. However, the practice does not involve pornography and is restricted to specific issues within the context of a marriage relationship.
Doesn't the medical community say that masturbation is a normal and healthy activity and can reduce the risk of prostate cancer?
Yes, the medical community does hold that it is a normal activity. And yes, some studies have indicated that it may reduce the risk of prostate cancer, but there is no consensus on this topic and it is a subject of ongoing research.
Is masturbation addictive?
Can the pressure to quit a masturbation habit lead to suicide?
Possibly. Like other social, cultural, or religious norms, extreme guilt over masturbation could, in theory, contribute to suicide. However, there are no studies that have rigorously connected anti-masturbation religious beliefs with a higher likelihood of committing suicide.

“Even though it’s not a big sin, a sin is a sin and addiction is addiction. It's going to weaken your spiritual life. Masturbation is natural, but so is “the natural human” and is still a sin. Try your best.”

“I don't have a strong opinion on masturbation itself, but I can say that porn is really, really bad for me. I've had a porn problem for a while and it feels like poison. Obviously masturbation is a part of that and I look forward to getting better at keeping the Law of Chastity.”
