Hi Yuva, The problem is that you are the drug, and its only you who can control these urges, but as men we get them, so its either dive into your work, get out and do something, or just get naked relax and enjoy yourself, but slowly and gently, dont rush at it.
If you can keep it to a couple of times a week your be OK your just keeping your system ticking over.
Good Luck
You're a young man and you do have hormones raging through your body. Masturbating is not going to make you get gray hair early.
