Do you know why I don't feel anything?

Sounds like a flat line to me. This is when your libido drops to nothing and you feel kinda blah(it’s more in depth than that) but it’s actually a good sign! Flatline means you are healing. It’s kinda like your brain has been exhausting itself for so long while you’ve been watching porn and the flatline is the nap your brain takes before waking up and healing. I recommend going to the your brain on porn website and reading as much as you can about the science behind porn addiction. They also have a couple of articles about the flatline. Good luck on your journey!
