You knock mister007’s source when the keywords to finding your first source are the following:
penis size;anxiety;micropenis;small penis;body dysmorphophobia;erectile dysfunction
Sounds likely to be biased toward the “it’s all in your head, don’t do it, it can’t work, owy, owy” .
Besides you were the one who dragged the penis surgery topic into the discussion. You keep leading the discussion away from natural PE. Why?
PE is about discovery and adventure. You don’t know it all. Let people hear the opinion of others so they can choose for themselves.
