Frankly speaking, most men (and women), if not all, masturbate especially those without sexual partners. Even those with sexual partners, like husbands and wife do masturbate also, when situations do not allow them to have sexual intercourse; like when a woman is with her monthly visit or pregnant and about to deliver her baby. In a clinic, a man is required by a doctor to masturbate when having a physical check up and evaluation in his capacity to bear children.
In the Biblical sense of righteousness, these situations can not be considered as sin. If a married man or woman, a bachelor, or a spinster, do masturbate to refrain from doing evil or infidelity to his or her partner, are you going to consider it a sin?

Scientifically, there are benefits of regular, and not overindulging,in masturbation. In recent study, researchers say that They found those who had ejaculated the most between the ages of 20 and 50 were the least likely to develop the cancer. They say that men who ejaculated more than five times a week were a third less likely to develop prostate cancer later in life. (

I do not recommend masturbation to anybody, neither do I encourage anybody to make it a scapegoat of their immoral sexual addictions, but I will not judge nor condemn anybody that because of force of circumstances, and not with evil mind, is doing the act. God judges according to the intents of the heart!
