Please advise as i am worried about it a lot [/INST] DearWe understand your concernsI went through your details. I suggest you not to worry much. Masturbation is not a sin. Masturbation is natural and normal and even animals do masturbate. But it should be under control. At your age of 18, you can masturbate up to one time a day. Decrease it to thrice a week gradually. Of course masturbating is tiresome.  That is the reason why you are feeling tired and the stress related to your masturbation habit makes you loose your hair and concentration. What is the need of medicine once you can overcome this just with the help of control? Just control your masturbation habit and for that you can approach a psychologist or sexologist. You can post a direct question to me in this website. Include every detail as much as you can. I shall prescribe some sexology related psychotherapy techniques to control your condition. I am sure that the techniques should be a success.Hope this answers your query. Available for further clarifications.Good luck. </s>
