This seems to only apply to the half of the population whose genitals would, or could be involved, however, this is never the case. Abandonment issues often arise from being taken away from adoring mothers only to be cut savagely. How many men have unresolved abandonment and or mommy issues? Doctors claimed for years that boys "didn't feel much"; they said there was a natural anesthetic from the birth process. Newborn organisms in need of nurture can't be compromised with anesthetics, so it validated the lie. Children feel it, yet, the cutting continues, for no good reason.
When one considers and understands that sexual assault can even be perpetrated by men in white coats, it changes the discussion. Just because you were cut does not mean your child's penis should look just like yours. The entire culture bears the legacy of all that betrayal, guilt and shame. None of that would occur and nurturing could continue right through the formative years.
Ask the child at the age of adulthood if he wants the end of his wanker whacked off and my guess is that he will tell you to step off!
