As a Doctor, i have probably given over 20,000 physicals in my career. I do physicals at 5 local high schools for sports, and do a lot of job and college admission physicals as well. Ive obviously seen a vast array of penises. Couple of points I thought you all might find interesting... about 2% have erections during their physicals. 99% of these are mortified by the event, despite any reassurances from me that it happens all the time. The largest penis I ever saw was about 8" flaccid. Ive seen a number that were less than 1/2 inch. About 85% are circumcised. I see little correlation between ethnicity and penis length or girth. If forced to pick which ethnic group is largest, I would say my experience says that those of Mediterrean descent, (Spanish Italian Greek) are slightly larger than those of Northern European descent. However, the largest i ever saw was on a boy of Irish background. There is absolutely no correlation between penis size and testicle size, or between penis size and height, weight, shoe or hand size or body hair. Be happy to answer any other questions about my experiences.
