Having always been naked around other guys, and born in the late 60's, I can say that of my generation about 80% of guys were circumcised. It surprised me later, once I was in the nudist scene, how many older guys were uncut; maybe 50%. I suspect this might be because the percentage of guys being cut depended where in Australia you were born.
In the present day, it's rare to see a guy under 35 circumcised, and most of those I know who have been had it done later after complications developed.
