There aren't all that many people who know what a moel does....he's he guy who carries out the circumcisions in an Orthodox Jewish community.
Now, leave aside such religious reasons and ponder whether we should be routinely using circumcision in the rest of the world?
We know that it does reduce the liklihood of getting certain diseases and cancers. But on the other hand, there's a thought that it reduces sexual pleasure by reducing sensitivity.
It's worth clicking through one of those links to see that the latter argument is false: circumcision almost certainly increases the sum of sexual pleasure precisely via that reduction in sensitivity.
