Quite possibly yes. Please don't take my discussion of masturbation as a commandment on the order of "Thou shalt keep thy hands out of thy pants" or something. Most mammals masturbate from time to time; excessive or addictive masturbation isn't very healthy, but let's not go back to the Victorian panic over masturbation and start insist that anyone who fondles their genitals will go blind!

(There was actually an organization, the White Cross Society, dedicated to stamping out masturbation. I'm sorry to say that it'll probably be revived sometime soon.)
