Question:

My psychologist assures me that masturbation is perfectly OK. I have also seen studies where medical experts maintain that masturbation and a robust sex life play an important role in leading a healthy life. Maybe the rabbis are wrong in their orientation to sex.

Answer:

Maimonides Hospital in New York is named after the outstanding physician and rabbi, Moshe ben Maimon, known as the Rambam. His book, "Mishna Torah," is a monumental compilation of Jewish Law.  In the volume, "The Book of Knowledge," he writes:

"Semen constitutes the strength of the body, its life, and the light of the eyes. Its emission in excess causes physical decay, debility, and diminished vitality. Thus, King Shlomo, in his wisdom, said, ‘Give not thy strength unto women,' (Proverbs, 31:3.) Whoever indulges in sexual excess becomes prematurely aged, his strength wanes, his eyesight becomes dim, a foul odor emanates from his mouth and armpits, the hair of his head becomes bald, and his teeth fall out. Plus he becomes susceptible to numerous other diseases. Medical authorities have stated that for each person who dies of other maladies, a thousand are victims of sexual excess. A man should thus be careful in this regard if he wishes to lead a happy life," (Hilchot Daot, 3:3.)

Also, kabbalists have stated that a person's sexual performance will wane earlier in years if one masturbates or otherwise misuses the gift of sexual fortitude, unless he endeavors in t'shuva (penitence) to rectify his past behavior.

This is just the physical side of the coin, without mentioning the spiritual dangers. A diploma on the wall and a medical degree are not the only things that matter when seeking sexual guidance. Also important in ensuring a healthy sexual life is true fear of G-d.
