[/INST] Degree understand your concerns went through your details. I suggest you not to worry much. You have not mentioned your age here. Any way, masturbation is not sin. It is a natural and safe procedure and even animals do engage in it. It is not harmful to emotions, concentration, memory etc. If practiced moderately (up to 5 per week) it is even healthy. Misconception about masturbation is anxiety provoking and is bad. Millions of male teenagers masturbate across the globe. How many of them are having issues like you. Very few, means negligible. Therefore, forget about the misconceptions about the masturbation and sex. Everything is OK until you overdo it. Everything shall fall into place. You may need sexological intervention. Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some sexology related psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck. </s>
