Some times you can be fooled.
I met a guy who was 6'5", had a nice bulge hanging down and I mean way down his left leg. When I got him home and got him naked, he had the biggest, lowest hanging nuts that I'd ever seen......................................... and a 3" hard dick. It didn't matter as he was one of the nicest and funniest guy that I have met.
PS. Size never matters to me, It's the personality that gets the prize.
