What is onanistic?

Onanism, also known as self-abuse or self-pleasuring, refers to the act of masturbation. The term is derived from the biblical story of Onan, who withdrew during sexual intercourse to avoid impregnating his brother's widow, and spilled his semen on the ground instead. This act was considered a sin in the Bible, and subsequently, masturbation has been seen as taboo or sinful in some cultures and religions. However, many health experts regard masturbation as a healthy and normal sexual behavior that can alleviate stress, aid sleep, and improve sexual function. The practice is also associated with reduced risk of prostate cancer in men.
