"As part of being untaught we take the attitude: If it ain't broken, don't fix it, ie, if there is no immediate problem do nothing. Only circumcise if something goes wrong - often reluctantly as a last resort after painful and prolonged treatment. This is in stark contrast to the rest of healthcare where the motto: Prevention is better than cure is stressed. There is a problem with thinking as we do. When does circumcision become necessary?
"There are a few situations where it is clearcut. If there is only a small opening in the foreskin so that passing urine is difficult, or when the foreskin is painful to pull back during an erection or won't return forward again. The latter is an emergency situation needing urgent surgery to avoid really serious consequences.
"But there are many other situations where circumcision helps prevent future disease or discomfort. We should seek to prevent problems arising, rather than deal with the problems once they occur. Let us look at some of these, in no particular order."
