Is masturbating once a week considered an addiction?

OF course not: Life is difficult enough without fools and crooks trying to frighten people over something like this. The "addition-recovery" movement has done much good but has its share of crazies. Most young people need to relieve the pressure from time to time, and even more, it's a natural way to learn about your body and perhaps imagine the person you will marry. You were brave to ask & i appreciate it.
