it's mastbating

Maybe, maybe not. If you develop a dependence, that is a different story and what many people are trying to break free of- including me.

 

ad·dic·tion noun \ə-ˈdik-shən, a-\
: a strong and harmful need to regularly have something (such as a drug) or do something (such as gamble)
: an unusually great interest in something or a need to do or have something

If you have to do it every day and I mean have to then you have an addiction, but I would say once a day is pretty normal. If you spend a day somewhere else than in your home do you feel like you have to masturbate?

 

Once a day is still regularly. If you have to schedule masturbation at all (once a day, once a week, once every 2 weeks) then you are still addicted imo.

 

Doing something in regular basis doesn't mean one has an addiction. Masturbation as an addiction is hard to define since it comes naturally to all of us (Denying it for religious or spiritual reasons is a different case, but they still have the urge at least in teen ages). My opinion is when it starts to be harmful to you in a way that it determines your daily routines then it's an addiction.
