Adam4Adam dick sizes are absolute nonsense. Do a little experiment: Search in all of Los Angeles or New York City and only limit the search to dick sizes 7.5+ inches. Pages and pages and pages of ads. Now search under 5.5 inches. Quite a difference. Apparently it's only hung guys who have joined A4A (sarcasm).
I've always held that 7" is the internet-lie baseline. I've hooked up with so many guys off A4A who have claimed 7"+ and they've mostly all been significantly smaller than that in real life. Sorry, you've struck my pet peeve here.
The problem is that when so many guys lie, bottoms *think* they can handle 7.5+ inches, but when a legit 7.5+" hooks up with them, they can't take it without whining or squirming because they're under a misapprehension about what that size actually is. The desire for a big dick is mostly fantasy because in practice the ability to handle it is often just not there.
