Two thing in your post don't add up. First you say your girth is 7" and then go on to say you've never had a problem with BJs.
When I was growing up and before the internet, I always thought I had a smaller than average penis. The only thing I could compare myself to was guys in the locker room. Now I'm quite small when flaccid but grow to 6.5" in length and 6.0" in circumference mid shaft. I've never had any complaints on my size and often received compliments from MPAs but I always thought they were just stroking my ego.
Then I was dating a this girl, and one day while giving me a BJ she said "you know you have a big cock, right?" Up until that point I'd never really thought so. I was just happy it works so well.
Now I suppose if the average circumference is 4.7" - 5.0" then yes, I'm thicker than most. I know for a fact that my length is long enough to hit bottom from time to time which isn't pleasant for either of us. But the thing I've noticed most is that some women have had a hard time giving me a BJ without their teeth causing some discomfort.
This gets me back to the two things that don't add up. Either
las venganza is exaggerating when it comes to his claim of 7" circumference or he's lying about never having a problem getting a BJ.
Shane Diesel is said to have a 7" girth. How is any girl to suck something that thick without their teeth getting in the way?

So I'm calling BS.
