Some people seem to be quite strong stubborn in their belief that a thing such as “porn addiction” exists. Allegedly you get “used” to certain aspects of your porn to the point where real life sex isn't “good enough” anymore. If you watch too much porn of women with unrealistically attractiy (and probably artificially inflated) curves then that “raises your standards”, or something.
While sexual tastes can be acquired, there is no scientific body on earth confirming that new tastes necessarily replace old ones. You will find plenty of “self help guides” with many products to sell and advertisements to run that will be more than happy to give you advice. Back in reality, however, such a thing does not¹⁾ exist²⁾.
The last person who told me about this imagined threat was someone who was extremely self-conscious and insecure who, I guess, heard about this kind of thing and without looking it up took it as an easy argument to somehow steer me away from porn - because there are women in there that she compared herself to?
