Male circumcision is prevalent in Africa mostly as as the norm. It is painless at childhood but gruesome when done to older kids. In some cultures around the world male circumcision is akin to piercing the ears of a baby girl for earrings.
In places where circumcision is a ritual, it gets done to older kids (early teens) as a rite of passage into adulthood. To me that will be more agonizing considering the awareness of the pain eg. when your dick gets caught in a zipper.
I personally dont find male circumcision at birth repugnant because I literally have no memory of it and I but I appreciate it was done to me appropriately.
According to https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5422680/
"The timing and reason for circumcision in boys or men vary across the continent. Circumcision is prevalent in as much as 93% of the countries in Northern Africa compared to 62% of countries in sub-Saharan Africa. Whereas the procedure is done for religious purposes in Western and Northern parts of Africa, it is seldom performed in neonates in Eastern and Southern regions of the continent where circumcision is, often, a rite of passage into adulthood"
What I'll love to see if the comparative AIDS footprint between countries with varying degrees of circumcision.
