Where does incredible sex come from? Mostly from your own libido, not even the act itself.
If the woman is good at it and she can amplify your base libido , well great, but if you're generally high-libido / strong erection then you can fuck a mediocre women and still have an amazing time.
Big problem with masturbation is pressure and speed applied on the dick , it's nothing like a vagina, another thing is sitting, we are not meant to sit(while coming) and we're meant to move our hips. Then comes the desensitization from pornography, it's extreme, too fast-paced and so on.
Another thing about pronography, it's solely visual and audio based, so no touch, smell, warmth etc. You get too used to high visual stimulus by watching it.
Another thing is the fact that pronography is essentially voyeurism. You rarely imagine yourself really doing the deed, you're rather enjoying two people going at it which is "hot".
But that lack of self-insertion is what drains testosterone, self-appreciation, libido and so on.
