Hey samrocks. You ask about the disadvantages of masturbating during the ages of 20-22 years. I have had some experience with masturbation and I've thought about your question for some time but I have not been able to come up with a single disadvantage. Masturbation in moderation at any age is enjoyable and harmless.
