It might be worthwhile to examine this phenomenon in a larger context. For example, I know a girl who is obsessed with watching sticky sweet romantic shows and movies like "twilight" and "the bachelor". The romance portrayed in these shows is extremely unrealistic and I feel it gives her unrealistic expectations of romantic relationships. Certainly there are no shortage of young men smoking too much marijuana and watching too much internet porn and generally not trying in life who wonder why they can't find a female partner, but likewise there are a lot women who are overweight, unclean, disorganized and generally not exciting (or even downright repulsive) watching romantic shows or reading sexy novels and thinking their world should be that way.
The larger phenomenon is, in my opinion, media substitutions for reality. It's like to much sugar and causes certain individuals problems. But it's not a problem isolated to porn and young men.
