I saw a urologist today. Interestingly, he said that he is very interested in all of this new thinking about how excessive porn use can cause ED. He actually encouraged me to try to not use porn for two months...though when I asked him about masturbating, he insisted that I continue to masturbate as frequently as I want, and at least 3 times a week. Though he also recommended using a lubricant because doing it too much without one can actually damage nerves. They tested my penile nerves and they're all fine, but he recommended using a lubricant going forward. I thought it was very interesting that "your brain on porn" is actually gaining some currency among established urologists.
