My wife agrees with most women that it is the skill of the user that is more important than size. She has enjoyed cocks from 4 inches to 8 inches, thin to thick. The one that felt best to her was about 7 inches and very thick. She didn't measure them, but bases her estimate on the size of dildos she has used.
My cock is 6 inches long but at the base it’s 6 inches in circumference. It’s strange as it gets thicker the closer to the base it gets. I have never gotten any complaints.
I got mine about 72 years ago. It was just a little nub back then. But I kept feeding and watering it, pulling on it every now and then, and it grew to a very satisfying size in a matter of 15 years or so. It's ideal for me.
6" circumference is about 2" diameter. It is a very good size any woman can't resist. Thats why nobody is complaining.
