Hello, Thank you for writing to HCM, Masturbation is for satisfy yourself sexually when you dont have any partner. But its good if use in some manners like no excessiveness or not be so much involved with some characters that you cant step out from it. Its a thing which people follow by their own way because people follow in what they are having more sexually satisfaction. As you decided to have masturbating by thinking of some characters nothing wrong in it but if you are too much excessive for that than its wrong. In your case I would say that if you think that you are too much excessive for that than suddenly stop it because after some times you will definitely like to watch porn and all normal thing what normal people does. Still if you had any queries you may concern a good doctor for more help they may suggest you better after checking you physically. Hope you will find it helpful. Thanks & Regards, Dr. Gaurav Prajapati
