How do you help a teenage boy to quit masturbation?

If he wants to quit make him play a sport or do an activity to help keep his mind out of it. Hope that helps

There's nothin wrong with a little self lovin' unless it results in semen incontinence or God discovers that he made humans with sex hormones. Also the young man's parents may find out which may embarass the addiction into submission. Generally, more wholesome activities should be sought, such as burlesque or dressing animals in homemade outfits or learning how to weild a sledgehammer or why the answer to the question is 42.

Yeah, and? Stress, then jerking, then....no stress. That's a hell of a lot safer than reducing stress with chemicals, unsafe sex, gambling, fighting homeless people, cutting yourself.....there's a lot of unhealthy ways people relieve stress. Masturbation is one of the few ways to feel wonderful with literally zero side effects.

Umm that's not going to be easy. It's in our nature to masturbate. I do and imma young teen. At first I thought it was bad and wrong but many people and adults say it's normal and not to feel guilty about it so you shouldn't try and get him to stop cus it's most likely not going to happen

You don't

Cut off his hands.

What is the purpose of what you propose?
