Some of you will know the porn actor Mandingo. He is famous for his penis size and I think he has biggest dick I have ever seen. (FYI: i am straight) When you people guess how long he might be, they come up with around the famous 12". My estimation based on some facts is much lower with 8.5". The rest of this posted is copied from another forum and i hope its appropiate to post a porno screen shot in this section of the forum. If not, please move it to the appropiate section. i estimate sizes by comparing it with other body features, which length you can guess better. i did this because i stumbeld across a video of mandingo where he in the middle of the blowjob strokes his cock and already has a pretty maximum sized erection. In the attatched picture i have made a screenshot of what i mean. now its time to compare. his fingers are near to the penis and are roughly the same distance from the camera, so we can compare the breadth of his fingertips (palm) there, with the length of his penis. when i blow the picture up all the way his fingers are 4.5cm (yes, i am european) and his cock has a length of around 13cm. now i take my hand and try to make similar grip around an objekt and measure the distance my finger touch it. i can come up with 7-7.5cm. this means his cocklength is 7*13/4.5 to 7.5*13/4.5 cm. when i calculate this its 20.3cm(very close to 8inches) to 21.7cm (8.5 inches). you can very well test this your own, by measureing the noted features in the picture and your hand breadth and putting it into the forumla. i think my hand measurement is pretty close to his, as our body types are pretty similar and he is roughly my size i would guess, compared to the girls (which thend to be tiny). for all of you who are curious i have 17cm / 6.7 inches NBP (18 if bone pressed, not really much of a fatpad) and with my body size it can look pretty big from the right angle. (i can post examples if you want). i hope with this realistic guess of the length of the all too famous mandingo, i have put your own (honest!) measurement in some meaning full context.i think, that in real life measurements huge (mandingo) means 8-8.5 inches and above average (my length) 6.5-7 inches. i also believe this study, which was done by pro familia in germany. there the mean penis length (measured by medical personel) was 14.5cm / 5.7 inches. even the longest they found was "only" 19cm / 7.5 inches among more than 100 men.
