For the first couple of years that I was getting blowjobs I had a pretty hard time being able to come from them. Many of the girls that gave me the head said it was never that hard for other guys to come when they gave them head, and they found it very frustrating. I never really put two and two together and thought that since I was bigger than most other guys maybe the girls had a harder time giving me adequate fellatio, because they were used to giving smaller guys head. Also, physically it may be harder for them to wrap their lips more proficiently around my cock. Have any of you guys had any trouble with recieving good head? And do you girls (or blowjob giving guys) have trouble getting the larger endowed men off?
