Recently, for a talk in Chicago to parents of high school boys, I had to update my knowledge based on a 2009 review of the effects of pornography. On this issue the world has changed a lot in less than ten years: the use of pornography has escalated and the effects are alarming.

The most telling effect, I think, is the epidemic of erectile dysfunction (ED) among men.  For all of human history this was mainly an older man’s problem.  As recently as 2002 the rate of ED for men aged 40–80 was about 13% in Europe. By 2011 rates reached 28% for men aged 18–40. As reported above, a 2014 cross-sectional study of active duty, relatively healthy, 21–40 old males in the US military, found that one third (33.2%) suffered from ED.

Unaware of these changes, for the last year or so I had thought that the drop in high school students’ rate of sexual intercourse was good news and that, since 2007, abstinence ideas were winning, but given the above data, all of the causes may not be good news. Increased pornography use among teenage boys, resulting in decreased interest in girls, may be the cause.

This also serves to put in context a disturbing experience I had a few weeks ago while driving through a wealthy Washington D.C. suburb during rush hour: I noticed (as must several other drivers waiting for the traffic lights to change) a 12-year-old moving along the sidewalk, intently looking at his smartphone in one hand while his other hand was engaged in self-abuse.  I had not yet reviewed the new research on the prevalence of pornography viewing and was quite taken aback.  No longer.

At age 12 he was already so addicted to porn and had no shame.  The average age of a boy’s first viewing of pornography has dropped to 10 years of age. Fathers be aware.
