- MCA,
Found this test to measure penis size/girth by fairly interesting questions. It thought I was a 7.5-8.0 (score of 32) ranged guy in length with a score of 50/50 for girth. Not so bad. Very few of the questions it asked had anything seemingly to do with my penis. Worth a minute or two of your valuable time. It seems like you have to sign up for something, but you don't.
