My two sons.
My godson (mainstream parents).
A friend's son (borderline mainstream/crunchy parents).
Another friend's son (crunchy folks).
And another friend's son (mainstream folks).
My nephew is circumcised as are the boys of our other mainstream friends, who had no clue people DIDN'T circumcise. The nephews on DH's side are all circumcised (three of them) though their father is happily intact. Go figure.
