Is it wrong for a girl or woman to want circumcised boys or men?

NO! I'm the same way myself.

It is relay rather silly though You obviously don't understand what the effect of genital mutilation of the male can have in both the short term and in the long run. Circumcised men are more prone to have any number of sexual problems relating to the desensitised nature of their penis and other problems.

Perhaps you should have a look at the related link below (Medical Studies on Circumcision) to help you make an informed decision.
