What is the smallest length gain that is significant enough to be noticed either by the owner of the penis or the ownee of the penis during sexual intercourse?
In length? Is 1/4 inch noticed? 1/8 inch? 1/16 inch? Or is it more like 1/2 or 3/4 inch?
In girth? 1/32nd inch? 1/16th inch? 1/8 inch? 1/4 inch?
And now what about for appearances sake?
