masturbation is a heck of a lot safer than raping people, paying for sex, ruining the beauty of sex by just F'ing everything, etc. You are aware of the thoughts going through your head and what you are lusting after...

watching porn supports the industry, keeps it alive, and reprograms your brain (watch it enough and you can't keep a boner in real sex, you will see). Being a pervert and masturbating are two entirely different things.
