You can't see any full length shots on that site, either you see the last couple of inches, or teh bottom of the shaft while his head is in some pussy or a mouth. But there's no way he's 11" unless he's over 7 feet tall, he does look pretty think though.

Jonah Falcon seems like a nice guy I guess, but I have serious doubts about his claim that he had 13". When he's soft he hangs forever, but I've only see one hard shot and I really wasn't that impressed. He didn't look that much bigger than me and I wouldn't have guessed it to be more than 9 or 10 inches. But if anyone has any better shots of his cock I'd be glad to reevaluate that statement.
