A) Masturbation is something you do when you're young, but then grow out of.
In fact, masturbation is a life long sexual activity. Surveys regularly show that anywhere from 70 to 95% of adult men and women masturbate. And while this may slow down as we age, many of us continue masturbating into our golden years. One survey of 800 adults over 60 found that that 46% of them masturbated, another found that 20% of seniors masturbated once a week or more. Masturbation isn't just for the young, nor is it an "immature" form of sexual behavior.
