If you drink too much water you will drown. Drugs, alcohol, and sex all must be done in the right way to maintain the health of the body. Abusive and excessive behaviors indicate the presence of the spirit of worthlessness. A lack of faith. Low self value.
Masturbation when done with the express purpose of birth control is anti-life.
Masturbation done in front of an image is lust and a perversion. And if a man has an emission of semen, he shall bathe his whole body in water, and be unclean until the evening. Birth control is based on the fear that man cannot provide the resources necessary for a good life for the child. God makes children. Lack of faith is truly the reason for birth control.
