I’ve seen lots of studies and they all have similar figures. I’ve also seen people refuse to believe them and call out some conspiracy. I struggle myself too believe the averages are what they are but I’m also someone who spends a lot of time and attention of my cock so I guess my perception is also distorted.
Rationally you can’t argue with the number of different studies all giving similar results. If anything the average seems to be shrinking with each new study as they become more thorough and leave less room for bias or misrepresentation. How much research have we wasted on this topic ha.
So, if you can accept the data, this question should be simple. One standard deviation above average would be noticeable larger than typical. Two standard deviations above average would be significantly larger and would be what you could confidently say is hung.
So taking average flaccid of 3.6” and standard deviation of 0.6” (first results of Google search), noticably larger than normal would be 4.2”. Hung would be 4.8”. 6” is 4 standard deviations above average and would be truly exceptional. I have trouble believing the numbers but thinking rationally we have to realise our perception is warped.
