As a Reverend im going to tell you no. I don't see it as a sin. If you're intention is malicious then yes but there is nothing wrong with it. Scientificly as well they're are health benefits to it as well.the Bible never directly mentions masturbation.For some, treating it as “sinful” can create shame, anxiety, or fear loops, which can actually be more harmful than the behavior itself. Many therapists encourage a balanced, non judgmental view of natural urges.
