Hello Thanks for query. You have been indulged in frequent masturbation 2-4 times in a day. Though it is harmless, excessive and frequent habitual masturbation does affect quality of erection and delays ejaculation.Please try to reduce the frequency of masturbation by keeping yourself busy in activities like sports,reading ,social work etc so that you will not get free time to masturbate. For acidity problem You can take H2 receptor antagonist like Pantoprazole twice daily Avoid spicy and junk food and include curd,milk in your diet.. Taking small frequent meals at regular interval of 4 hours instead of having 2 full meals will help to resolve the problem of acidity. Dr.Patil.
