I have had a funny experience in the swimming bath. After swimming I used the showers as usual. There were some guys in the showers and I noticed one of them watching me. ok, nothing funny till there. I left the showers and went to my locker. While chaning my dress I heard two men talking on the other side of the cupboard wall. I heard them talking about my penis. They guessed my dick to be more than 20cm (nearly 8") and wanted to see it erect, beacause they thought my penis as the biggest they had ever seen. The funny thing is that my cock is not 8" long when soft. It's only 5" soft. Perhaps after the warm shower is was 6 maximal 6.5" long and they guessed it would be more than 8" long. I think this experience is a good example for wrong estimates in penis size.
