I figured out a while ago that porn is a drug.
Just like with drugs you start easy with soft core playboy pics, but then that doesn't do it for you anymore.
Then you move onto penthouse, then hustler, then hardcore videos. Next thing you know you need to watch transsexual midget bondage scat cartoon rape porn to get off. Codeine -> oxycodone -> smoking heroin -> injecting heroin, need to take heroin just to feel "normal"
Meanwhile, real women seem don't elicit the same passion in you, and sex not as good as it used to be, even sometimes you might not be able to get it up, and if you do you can't cum. Hence, why so many young guys these days increasingly are using viagra. After a daily diet of hardcore fucked up niche categorized porn, the real thing just doesn't stimulate you the way it should.
Before the modern era of porn, the average guy maybe saw 5 different pussies per year, now with internet porn you can see 100 pussies in 10 minutes. This overstimulates the brain and desensitizes it, just like taking meth overstimulates, and when coming off meth the world is a dull, depressing place until your brain recovers and re-sensitizes the receptors.
I'm sure just like with many drug users, regular daily porn users have tried to "cut down" or "quit" using porn at times in their life, only to realize how addictive it is. Many even experience withdrawal symptoms such as insomnia and mood problems, which go away once they get their porn fix again.
Do you realize all that imagery from porn is being stored in your subconscious and is affecting your everyday interactions with other people? That secret shame of looking at twisted porn is sitting just below the surface of your mind and is affecting your confidence, integrity and other aspects of your self.
As with everything, moderation is key, but not many people can take addictive drugs in moderation. Especially addictive drugs that are free and can be taken in secret at anytime in the comfort of your own home.
