I am student of 10th class usually active at physical activities and busy schedule of studies but i can't resist my addiction of mastubation! quit it.

I'm concerned about: your use of capital letters to begin most words. In contradistinction to the obsession with your privates you may not ever become a great communicator if you do not become more mindful of your use of caps and proper punctuation. In time this too will come.

As long as your: activities are not interfering with your social or academic life, it's not something to worry about and is normal behavior. If masturbation is interfering with your life, then there is likely an underlying reason (such as anxiety or depression) as there's no such thing as masturbation addiction, porn addiction, etc, and I'd encourage you to speak with a mental health professional.

See a psychiatrist.: It sounds to me like you are very driven and has a lot of energy and masturbation maybe a way of relaxing an d reducing some of your drivenness. A psychiatrist could evaluate you and see if there are other psychological causes behind your masturbation.
