Mandigo is crap. Lets be honest.

If you think Mandingo can't get girls to come, or that he hasn't made videos where the girls are obviously getting insane pleasure from his HUGE dick, I've got a couple of videos you need to see.

Which ones did you have in mind? The first one of the 'good' Mandingo scenes I can think of is the one with Christie Lee in Flesh Hunter #6.. She seems pretty much genuinely excited by his size.
