To answer both of you my friends, NONE OF TH ABOVE.
And the best way to understand the problems with adult entertainment is to draw a parallel to drug consumption.
Wether you use adult entertainment for pleasure or as an aid to have an erection, is the same. Picture the extremely busy guy that loves to party but has a lot of work and is making decent money. And in order to function properly and wake up early in the morning after a crazy night of drinking heavy, he snort just a tiny bit of cocaine. Perfect! He is able to perfectly function with his life that way. After 6 months, he needs a tiny little bit more to get the same effect. At this point, you talk to him, and advise him how dangerous drug use to function is, the long term side effects, the potential health hazards, the addiction, etc. He proceeds to explain you how under control he has it. Is just a tiny bit every morning upon waking up and he functions perfectly normal the whole day and is able to party the next evening. So you believe him, he might have a stronger mindset than the average.
But as time went by, that tiny bit needed kept increasing. Because as always, as with anything, the body builds tolerance. So he needed more. And more. And because he was crashing hard in the evening after work, he started doing little bit before going out too. Long story short, when he realized that what he was dong was perhaps not the right way to go, he tried to cut it off. He couldnt. He was barely able to drag himself out of the bed, his whole body aching, weak, lethargy, foggy mind, he was vomiting anything he tried to eat, he had to snort cocaine again. His brain chemistry changed, and he started developing panic attacks from the idea of feeling bad again, and he started taking a little bit more. Now stacking it with xanax to be able to sleep at night.
And long story short, that is the addiction process. With adult entertainment is no different. Down the road your brain will require more, and more, more hardcore, more nasty, more pervert, and this is the reason why we have so many multiple categories of adult entertainment available. Because when nothing else works, you are going to end watching girls eating shit, which is not even adult entertainment anymore (for a normal brain) but in a twisted brain, already consumed by adult entertainment, new fetishes and perversions are born.
And we dont even need to mention real sex. True, on the early stages of adult entertainment watching, it perfectly complement your sexual lifestyle. But as the adult entertainment volume and variety keeps increasing, it comes to a point in which it surpasses a real woman naked. Suddenly the addiction is so deep that a real woman to make love with her does nothing in terms or arousal and excitability. As a consequence, there is no erection. And of course, throughout the process the issue starts with a decreased EQ.
