Masturbation is something that many people have experimented with. And many don't believe there is anything wrong with it. A question that is often asked is "Is masturbation mentioned in the Bible?" The answer to that question is "no". Just because the word masturbation is not mentioned in the Bible as a sin does not mean that the behavior itself cannot be sinful…
Matthew 5:28 But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.
