I'll tell you how relevant it is...lil Tow#1 was done when he was born...I always said it didn't look quite right. So anyway, skip forward 12 years, he comes down stairs FLIPPING out because he was red and swollen and developing an infection. Apparently, boys don't have the greatest hygeine habits, even after parents preach the importance. Long story short, at 12 years old, he had to have it REdone because there was too much foreskin left from when he was an infant.
So yes, even today, hygiene is a major factor.
