5 Health Benefits of Masturbation | Men's Health News

This is from a trusted source and is aimed to average men who are generally healthy. Your two sources are directed towards those who are mentally ill and currently dealing with depression. Also, "Your Brain on Porn" is clearly not a website that supports the viewing of pornography, in fact, it's not even talking about regular, healthy pornography or masturbation, it is aimed for people who have an addiction to the above and is more like WebMD which will only tell you that you have some disease you never knew you had. Your Brain On Porn will not tell you that masturbation or porn is okay, it is meant to scare you.

edit: And the second source wants to sell you something. It'll tell you that your life is in a downward spiral and if you buy their books and pay for their "professional" coaching, they will cure you of your bad habits.
