I have. Twice in fact. Once out of curiousity, and once because I was asked (I'd forgotten my previous measurement).
EDIT: I wonder if there's any correlation between size and willingness to measure. I'm generally a curious person, so I did it just to see where I stand against everyone else. What I'm more curious to find out is whether the 5.5 inch average includes fatties, because overweight men actually have longer penises than what you can see (to understand why this is, blow up a rubber glove and watch the fingers shrink). If they only account for the visible length of the penis then the inclusion of fatties in the sample would lower the average, making the average for non-overweight men probably closer to 6-6.5 inches.
In any case, every girl that's ever seen/touched mine has said it's big (I'm fairly tall, so it's to be expected), but I'm sure every girl says that to every guy they're with just to boost their confidence, so you can't trust their word
Don't lie girls, you know you do.
