Before PE I've always been at about 6" diameter at the base (5.75 head, 5.5 mid-shaft). In the 42 years (first 10 ten years I never passed on the chance) of sharing my penis, intercourse was never a problem with the diameter. Dryness, yes, sometimes. Since PE, I believe I've had some gain (haven't measured thickness in a while) and my wife enjoys it.
