Thank you, you listed good points, which are also valid for other addictions or distractions we can choose in life. Porn is a special one because it adresses one of our lowest instincts and it's known what's happen if men (speak of myself) have a long withdrawal of sexual activity. Porn almost instantly stimulates these low instincts and spreaded like a virus "thanks" to the internet. Although it is so attracting to men, we still can decide to watch or not. It depends on the character of a single person how often and how long such movies and picture will be consumend, same as with alcohol, cigarettes, TV, games, coffee and many more. I'm no drug expert but what i know there are many differences and some real drugs among my list, which are very addictive.

In France the orgasm is called le morte or the small death and that's true for men because they need time to regenerate after such event.. which sometimes women cannot understand ;). If a man has many orgasm, maybe multiple times a day he will fall into lethargy because the sexual drive is completely gone and from what we know it's one of the central forces to drive men forward not just in direction of a partner also for success in business, sports, it's a fundamental force of human nature.

If you read "Think and grow rich" by Napoleon Hill there is a whole chapter about sexuality called "The mystery of sex transmutation" which describes how sexual impulses are like pure energy which can be transformed into other energy forms for example to run a successful business, to generate great ideas.. the basic idea is that is like i wrote before a basic force which drives us as human if we not waste this energy with things like porn.

And now back to your topic, if i constantly drain this energy source with primitive satisfaction by consuming such media then nothing remains, just a empty shell, the same like if i watching TV multiple hours each day i think. It's like a sedative which holds someone constantly on a low level with nothing which can stimulate his mind and body because there is no urge or desire anymore and that leads to lethargy and insignificant life i think. I compare that also to someone who is addicted to pills or consuming the whole day cannabis or alcohol. These people are constantly in a calm state with no energy.

And yes that can be dangerous if you're not aware of what happens. The gray matter is suspicious to me because it's a old saying, like "if you masturbate you get dumb!" or like the recent McDonalds advertisement "Sex makes one blind." I think the gray matter theory could be true because of all the negative side effects because of the lethargy which happens if someone consumes such things in huge amounts.

I recommend to split such long text blocks in the future so readers can easier digest it, but of course it's your choice. Thank you!
