Don't be too hard on me here.
The question was initially addresed to SB, who I know has been married and faithful (so she says, at least) for 25 years, so back in her wild days almost every guy probably had one.
And Apple & TIS, I'd guess, altho single today, are probably not exactly, um, hanging around with the younger generation.
But even if I was asking someone younger, I don't think that my question has the implication that you suggest it does.
(and if only 20% of American me today are "intact", that percentage isn't gonna shift to anywhwere near a majority in the next 20 years.
If there are presently, say 100 million men in the U.S., and 80 million are circumcised, and 20 million of them die die in the next 20 years, that will leave, 80 million, with 64 million circumcised.
And if they are replaced by 20 million, 16 million of whom are not circumcised, that will still live 68 million out of 100 million who are.)
