Whats weird is that I can grab my dick with both hands then take the bottom half of and stack it on top of the other hand and still see the whole head.
Another example of a true two hander cock.
You probably know Matt Hughes (aka Danny Dong) has a monster white cock.

Like Mandingo, Matt Hughes also has a true two hander cock (see attached pics). Once again, note that the hands are placed over the shaft only (not over the ballsac nor over the glans).
Both hands around the shaft: that's the definition of a true two hander (huge) cock.
And last: in the attached pic "Danny Dong vs average penis" you'll see the difference between the huge cock of Danny D and the average size penis of another porn actor.
If you have an average sized penis you cover the whole shaft with just one hand.
But, if you have a huge cock (like Danny Dong or Mandingo's cocks) you can place both hands around the shaft leaving the glans exposed. That's why people know Danny Dong has a huge cock despite he hasn't ever measured his dick on cam.
