I think most here know that size matters just like height and weight-lifting matter, but how much?

I don't want feel-good nonsense about how you can make a small penis somehow "work."

I just want the truth, and this is the best place to ask. Perhaps people with average or small penises can share their experience, but all perspectives are welcomed.

Edit: I am 6 inches long and have a circumference of 4.5 inches.
