Masturbation is natural, healthy, and only an addiction if it critically impairs your ability to function personally, at work or school, or in public.

You're young, you're likely just beginning to develop sexually, you will have kinky thoughts you've never had before. It's perfectly normal to have kinky thoughts even if they are a bit disturbing (that's typically why it turns you on in the first place). And you are most definitely not alone.

Don't confuse yourself. You are normal. Your thoughts are normal. Your wanting to have sex is normal. Your masturbation as a sexual outlet is normal.
