Yes, but you are talking about situations in which people are openly sexual, something that is alot easier for men who are more well-endowed and more likely to feel confident enough to expose themselves to the public. I stand by my opinion that the average man is a hair over 5.5" erect length.
I worked for many years as an orderly. I saw alot of penises, too, and not in sexual, social, party situations. Just regular guys. Only a couple men during that time impressed me as being large. Both were very thin, somewhat tall caucasion men. One of them was big. The other, an older gentleman, had what I would estimate to be a 7X5 FLACCID HANG!!! Maybe he was a shower, but still...it was huge.
I don't have the size hangups that some guys here seem to have... and I wonder why we put pressure on ourselves to conform to some unrealistic ideal penis size? I do Penis Enlargement exercises because it works and I think it is awesome that I can make my penis bigger, but I'm not doing it because I feel like I must conform to some unrealistic standard to be a he-man.
5.5", guys. Don't make yourselves miserable.
