It’s a procedure in search of indications. Unethical and surprisingly still common and covered by insurance. No doctor would perform aesthetic surgery on a child for any other reason save ear piercings, i don’t think it’s as common as it used to be, but an infant couldn’t consent to that either.
For some reason, I’ve encountered lots of moms (occasionally would get a “hell no” from dad though) whose biggest concern after their son was born is when the circ was going to be performed. I wish the medical organizations would put some more focus on the ethics and aspect of consent/assent. There’s a lot of talk about research in public health about how it may or may not affect STI rates, and then the argument gets stuck on risks/benefits rather than ethics.
It ultimately is a procedure rooted in cultural and religious practice, and the American medical establishment is pretty slow, especially in that aspect.
From the outside looking in, I feel there’s a lot of aspects of trauma and mental health problem that can manifest in kink, sometimes as a beneficial way of overcoming these issues, but I think there’s a lot of maladaptation in it, and the space allows folks to intentionally or unintentionally reinforce harmful thoughts and behavior.
I think even beyond the kink aspect, this is seen in sexuality generally. I’d say the best other example would be the idea of “bottoms” and “tops” as almost personality archetypes and rules of behavior rather than sexual preference.
