This is the best survey of the subject I think I have seen, and I have put off answering to think a bit about the categories. Its a question thats been on my mind since I was a teenager, as I was convinced that I was different from everyone else, so I have been comparing with others ever since. The drawing is excellent and you can see pretty exactly where you fit in. Its probably an advantage too not to put in too many gradations in each category, as they make interpretation difficult.
Though the survey is about erect sizes and shapes, but question G, skin coverage, seems to be about the flaccid penis, or that seems to be how it has been answered. Obviously this makes a huge difference, someone could be G8 soft and G1 (not circumcised, but with no skin visible) when erect. Perhaps this should be pointed out.
For the shape of the glans, which can vary so much from one individual to another, three categories may seem not enough, though the parameters chosen are completely unambiguous. For example, for those that are elongated (2 longer and thinner), some are not very wide at the corona end the torpedo shape you sometimes see, whereas others are very wide at the corona end torpedo with a rear flare. In addition, there is a noticeable difference in the flaring of the corona for all shapes, which can be very pronounced in some cases, especially when erect.
Last point when the final version comes, put measurements in metric as well. I know when I convert in my head it can be less accurate.
Here are my measurements, as best as I can do for now:
A 4 - not quite sure : head is a good bit wider than shaft; why is A5 larger rather than just wider ?
B 2 - long, but much narrower at the tip than at corona
C 1
D 1
E 2
F between 1 and 2 - it's quite a pronounced curve to the left
G 4 flaccid, but no skin visible at all when erect (partners have thought I was circumcised)
H 5 7.25- 8 inch at most
I 5 about 6 inch
J 4
