Dude, masturbating in front of a computer screen is not a natural behavior. The nature argument is that men get more aroused by visual stimuli, not that they prefer the virtual to the actual. If you spend all night surfing the net when there is a live woman in your life,  you don’t get to play the "nature card."

Honestly, can you imagine our primeval ancestors, staring at pornographic cave paintings rather than chasing live women?

"Me Tarzan. You Jane.
You not Jenna Jameson.
Jane, go away."

I don’t think so.

Besides, just because a behavior makes evolutionary sense, doesn’t mean that every instance of the behavior has survival value. The existence of the "fight or flight" syndrome doesn’t mean every bar room brawl has survival value for the individual who does it.

The key moral insight in my book, Smart Sex, is that it is always wrong to use another person. If pornography use is causing you to use other people, you need to make amends to those you have hurt.

If someone you love confronts you about your pornography use, take them seriously. Dr J. says so.
