In probably 80% of people, masturbation is NOT an addiction.
They practice self pleasure, enjoy it and it is all very healthy, and stimulating.
It is an addiction if you actually are addicted!
It is an addiction if masturbation sessions are too frequent, you don’t like it, want to stop it but can’t.
Now, in most people’s lives, masturbation is simply a healthy sexual practice and it is perfectly ok and encouraged to keep exploring it.
