Do masturbating daily can affect health of a person?

It's a good thing: If you are obsessed with erotica and this is interfering with what you realistically know you must do or should be doing (work, relationships with real people), get with your physician now; it's treatable. Otherwise, it lets you learn about your body & mind to prepare you to be an adult, keeps you comfortable and focused. Think about the girl you'll marry, and good luck.
