I think the categories are wrong. Anything above 7" is a horse dick?
What about 8" and horse sized? That seperates it a bit.
Anyway a while ago I did some research on Google to find out what % of men had a 9" dick (recent obsession due to my bf) and it was 5%, or 1 in 20 if you prefer. Just like a First class degree!
Personally my penis karma has grown in my last three partners over 10 years. They have gone from average to large average to 'omg I'm getting married'.
Many guys have above 7" dicks anyway. I just think the size clarification should be better, you know for science purposes and that...
