Yes..that is his official "stage name" Fred Nice is he real name as far as I know. And as for how amazing these girls are who take all of Mandingo - it's not really that huge of a deal. You guys really do need to realize how f-ing tiny - male and female - most of these adult stars are.
It still looks impressive none the less - but wouldn't have the same impact with a normal sized girl or even with a average sized guy with Fred's cock. I have these porn girls over to my house every week and am still amazed at how tiny they are every time I meet a new one.
I know lot's of girls who have worked with him - hell Layla took him and Jack Napier on at the same time - and I used to attend a adult swing club here in town back in the day that Fred used to hang at before he really started doing films so I know of what I speak. While he was of course big, it wasn't the talk of the club or anything. I've seen quite a few normal (non porn star) women take him no problem.
Again not knocking him at all - huge cock for sure - probably the biggest working in the biz at the moment - but his diminutive size really makes it stand out on screen and then put it next to a girl built like a 12 y/o with implants and you have quite an image.
