I couldn't agree more with Cannibal Lector and Proudly Italian. You've both hit the nail on the head in your messages. I consider myself much bigger than the average porn star because I have unusually big girth. But, nonetheless, there are men out there who could put most male porn stars to shame in the "big dick" department. Also, I get really pissed off when some of these men in porn are known for their big dicks; that it, "big dicks" they don't even have.
One can easily come to the conclusion that I'm rarely impressed with the dicks of any porn star (there are few well-hung ones that are somewhat impressive), but the vast majority have no reason to walk around thinking they have one of the biggest dicks in town. They need to check on LPSG.org should they want to see some "big meat". Don't get me wrong, there's a few here and there who are what I consider "well-hung", but it is very uncommon for me to be "impressed" by any porn star's dick.
By the way, I don't think straight porn is about "big dicks" like it supposedly was years ago. You always hear now that dick size is usually an irrevelant issue for becoming a straight male porn star. Go figure?
Finally, it is true that gay porn seems to have a better understanding of what a "big dick" is. But, even if gay porn, I find most dicks are overrated. But, gay porn stars do have bigger dicks in general than their straight counterparts. I will argue in favor of that point for sure. The only problem is: I don't care for gay porn, apart from seeing how big the men's dicks are. Damn!
