Well, I have a 7.5 inch girth and it is been impossible to penetrate at that size. I didn't pump at all when I have had sex since I have been that size, and it was freakin' comical how my cock would collapse like an accordian at the entrance, going nowhere! I would manage to get a 6.5 inch girth inside, but it was very painful for me. It felt like my cock was having the life squished out of it. I have even tried penetration at 7 inches in girth, but that didn't work at all. It would take a geneticly large woman or a woman who was in the business of stretching herself out to accomodate my usual 7.5 inch girth, I am waiting on that woman. 8 inches is damn near impossible for all but the extremely adventurous, I should be there sometime in 2007 or maybe 2008.
