I agree with auntiejessi about this - it may not necessarily be an addiction. Young guys often have high sex drives due to high levels of Testosterone & masturbating once a day doesn’t sound excessive to me at all. In my teens & early 20s I prbly masturbated about 10 times a week on average, maybe once daily some days, skipped a day here or there & other days more than once, especially on weekends. As she points out, if it’s not a total obsession & isn’t interfering with other aspects of your life, it prbly isn’t an issue.
Why do you call it an addiction? Have you taken any steps to get help?
I hope others will come along, too, who share this issue.
