Most of the "literature" (in my day Penthouse Forum!) talks about length, not so much about girth. Women told me firsthand how big and thick my cock was, but it was only when girth size statistics were published online that I realized just how rare 6 inch and above girth truly is!
I really love being thick enough that it is noticed and fills a woman up, but I'm also glad I'm not in the 7-8 inch category!
I remember this exact thing happening. I always felt that I was not a rock star in the length dept, but seemed to be relatively thick.
70s and 80s, even 90s porn talked about length way more than girth, and still does. One time I read in a penthouse reader question, what girth percentiles and stats were for men, rather than length.
That was the first reference to circumference measurements and averages that I ever heard. I was slightly smaller then, at 5.75" girth, but to be confirmed as thick was nice. The last metric listed was "over 6 inches" meaning that 6 and above was very rare (less than 1%, by that study).
7 inch girths were not mentioned.
8" girths got laughed back to the boyhood fantasies they originated from
My real hope here is that we can help all the women of the world through this issue of whether or not they can "take 8" girth."
