I have seen him in some vintage porn vid when he was much younger and he wasn't half bad looking. Plus to be a porn star you have to be able to get hard on demand. So it doesn't matter how big a stud you are if you cant do this. Apparently as mentioned above, he can also come on demand. So he more than fit the bill for male porn star. (Lucky git!)
Apart from that he probably is a fairly friendly charismatic character which served to prolong and maintain his career in the industry. I mean he is the normal guys champion! We all tend to think if he can bang that many gorgeous girls , so can we!
