Could masturbation affect your health?

It's good for you: Essentially all male and a majority of females enjoy their bodies while alone. It keeps you comfortable and able to focus on other things, and prepares you mentally and physically for adult roles. It won't make you sick, fat, short, hairy, smooth, infertile, or an unfit husband / father. Anyone who tells you otherwise is misinformed or worse. Think about real love rather than internet junk.
