No doubt there will be a few women disagreeing with me but I think the whole 'measurement' and 'size' thing is a male hang up. I have lost count of the number of pms I have received from guys asking me to come admire their goods! They usually say things like: "I am told I have a large penis but I am not sure if that is true. I have some pictures here. Could you come and have a look at them and leave comments?"
Then when you go over there, you find TONS of comments from people who have already been there! If dozens of people have told a guy he is hung, what does he need my opinion for?!
I personally have never slapped a tape measure on a guy's Johnson. I take my cues from how much he excites me in the sack. If he has what appears to be a satisfying dick, even better but he has to be able to put down the right moves in bed. That's more important in my opinion.
