hi I'm 17years old boy,and I'm virgin still. and since last 2-3 months I'm masturbating 4 to 5 times a day, and if i don't masturbate 4 to 5 times then my penis gets erect. i even can't talk with my female college friends also. now, is it ok or I'm suffering from any disease ? please help me. and is it ok for my health to masturbate 4to5 times a day???
