Hello dear, First of all, remove all misconceptions regarding masturbation from your mind. It is a normal phenomena, and does not have any side effect on body or mind, unless you get addicted to it. HIV is transmitted sexually if one performs unprotected sexual intercourse with an infected person and not through masturbation. Since you are feeling that masturbation is interfering with your normal functioning, you can try out the following measures: 1. Improve your social life by spending more time with friends and relatives. 2. Keep your mind active and busy at all times either through curricular or extra-curricular activities. 3. Have a diet rich in fruits, vegetables, fish, nuts & honey. 4. Avoid fast foods & lipid containing diet. 5. Avoid smoking & alcohol. 6. Keep away stress, think positive. 7. Exercise regularly & practice meditation. 8. Avoid pornographic contents on internet. Wishing you a healthy life. Take care.
