Hello, Thank you for writing to HCM, I had gone through your query and found that you describe that your female room mate says normal people don t masturbation. So, I would like to suggest you that its nothing like that but even normal people masturbate for satisfy yourself. Masturbation is for satisfy yourself sexually when you don t have any partner. But its good if use in some manners like no excessiveness. Its a thing which people follow by their own way because people follow in what they are having more sexually satisfaction. It should be good for satisfaction for sex but excessiveness may occurs some problems for your body like weakness and so on. So, its better to masturbation for no excessiveness. Still any queries i would suggest to concern a good doctor for more help. Hope you will find it helpful. Thanks & Regards, Dr. Gaurav Prajapati
