Do not believe the erroneous information you hear from the medical community. I am 50 and caught herpes when I was 20. Over the last 30 years and many dozens of outbreaks I have noticed that my sores only develop on the skin formerly covered by the foreskin. My father had himself circumcised at 21 because he said his foreskin pulled back only manually.
I was circumcised (butchered) as a baby, so I do not know for sure, but because "I am quite wide" I suspect I would have inherited the same retractability issue my father had. If my foreskin was only manually retractable like my father's, because herpes comes up on the points of contact and all my soars come up between my circumcision scar and glans, it stands to reason that I (at least) would not suffer outbreaks. It is also possible that difficult to retract foreskins developed (via evolution) to protect those people who are particularly susceptible to herpes. BTW, I have never been able to be married or have children because no woman has wanted to risk getting herpes. I have been alone for the last 30 years.
Many people are infected with herpes and don't ever show symptoms. That may be because the virus can enter the body through the shaft skin and outer foreskin which the virus does not like as much as the mucous membrane that lies on the underside of the foreskin. If there is any chance I am correct, please heed this advice because herpes can ruin your son's future sex and family life.
