When I said that porn was a root cause of depression, social withdrawal and social anxiety, of course the dots of color on the screen aren't the problem, but the world of porn, which broadcasts the message that if women liked you they would take their clothes off for you, becomes alienated from the real world, leading to social withdrawal and social anxiety because when women aren't enthusiastic about flirting etc. it is interpreted as meaning that you are unattractive and inadequate and that the only way to see women in the nude is to watch porn where the women can't reject you. And it is embarrassing to be joining a social tennis club with the sole purpose of meeting a woman who would undress for you.
The only nude photos on my computer (17) I downloaded in a few hours last July. I deleted them all early this morning making a point of throwing out backup CD-ROM versions too. It was a close thing to keeping them. After tossing them in the garbage I had the best sleep in years.
I was a heavy user of videotapes and magazines as a teenager in the 1980's. I couldn't talk with the women in the videos and became socially isolated. At one point I planned to lose my virginity with a prostitute the next morning and then kill myself (I became a Buddhist 3 years later and have never been suicidal since.) I suffered from bipolar disorder since puberty at age 14 which I had blamed on unrequited love but I believe that poor sex education on the topic of pornography was a factor.
