True. I always assume there's no point anyone should be bulshitting surveys. I guess I'm still naive.
I wouldn't understand why anyone would lie about their penis sizes, especially in an anonymous environment like the internet, but they do, that's the truth. Hence, I can't take any of these self-surveys much seriously. They are interesting and worth a read though, just nothing more.
Also, I feel there's a certain bias that men with larger penises are more likely to share their sizes/volunteer to get measured. So, actual averages probably work out much lower than any of these limited surveys.
