Seriously though (from ye olde

It is held in many mental health circles that masturbation can relieve depression, stress and lead to a higher sense of self-worth (Hurlbert & Whittaker, 1991). Masturbation can also be particularly useful in relationships where one partner wants more sex than the other — in which case masturbation provides a balancing effect and thus a more harmonious relationship.
In 2003, an Australian research team led by Graham Giles of The Cancer Council Australia concluded that frequent masturbation by males appears to help prevent the development of prostate cancer. The study also indicated that this would be more helpful than ejaculation through sexual intercourse because intercourse can transmit diseases that may increase the risk of cancer instead. Also, frequent ejaculation is more easily obtained and sustained over time with the aid of masturbation.
A study published in 1997 found an inverse association between death from coronary heart disease and frequency of orgasm even given the risk that myocardial ischaemia and myocardial infarction can be triggered by sexual activity. Excerpt, "The association between frequency or orgasm and all cause mortality was also examined using the midpoint of each response category recoded as number of orgasms per year. The age adjusted odds ratio for an increase of 100 orgasms per year was 0.64 (0.44 to 0.95)." That is, a difference between any two subjects appeared when one subject ejaculated at around two or more more times per week than the other. Assuming a broad range average of between 3-5 ejaculations per week for a healthy males, this would mean 5 to 7 ejaculations per week. This is consistant with a 2003 Australia article on the benefits against prostate cancer which is referenced elsewhere in this web page. Source {"Sex and death: are they related? Findings from the Caerphilly cohort study", BMJ 1997;315:1641-1644 (20 December)}
Masturbation is also seen as a sexual technique that protects individuals from the risk of contracting sexually transmitted diseases. Support for such a view, and for making it part of the American sex education curriculum, led to the dismissal of US Surgeon General Joycelyn Elders during the Clinton administration.
Many people see masturbation as an effective, natural cure for insomnia. Sexual climax, from masturbation or otherwise, leaves one in a relaxed and contented state. This is frequently followed closely by drowsiness and sleep - particularly when one masturbates in bed.
Some people actually consider masturbation as a cardiovascular workout. And while doctors have no proof of this actually being true, those suffering from cardiovascular disorders (particularly those recovering from myocardial infarction, or heart attacks) should resume physical activity (including sexual intercourse and masturbation) gradually and with the frequency and rigor which their physical status will allow. Some doctors will advise those recovering from heart attacks to abstain from sexual activity (solitary or with a partner) until one is able to climb two flights of stairs without experiencing shortness of breath or chest pain. This limitation can serve as encouragement to follow through with physical therapy sessions to help improve endurance.
