Circumcision
An entirely legitimate procedure done with a male child, usually at birth, that involves cutting off the excess foreskin of the penis. Those who have not been circumcised are required to pull back the foreskin over the head and clean it, if this is not done early in life (which is entirely possible due to that the United States only accomodates for circumcised men, that they never show pictures of uncircumcised penises when a child is studying Sex Ed so the uncircumcised boy doesn't know what it's supposed to look like) then the ligements in the penis will bond to the foreskin and the skin will have to be medically pulled back by anesthesizing the head and scrotum with an epidermic needle, which is equally painful, if not moreso, then having the foreskin completely cut off at birth.

The foreskin has one rewarding factor in that it increases sexual pleasure, but most uncircumcised men will never be able to experience that due to the bizarre and gross appearance of the penis (seriously, it looks like a saarlac) that will disgust the woman.
“Ah!” Sammie yelped “You think my vagina’s gross! What the hell’s the matter with your penis!?”
Jack looked down at it “I’ll tell you what’s wrong with it, society!”
“Society made your penis look like a sarlac?”
“No” he pulled his foreskin over the head “It used to look like this.”
“What happened?”
“I already told you, society!”
“That still doesn’t answer my question!”
“Okay, my parents didn’t have me circumcised when I was born.”
“Why would they ever do such a thing to a young child?”
“I know, right!? Now I have to suffer for life, as opposed to the few short seconds that I would have as a child.”
“So why don’t you just get it taken care of?”
“Because it hurts.”
“So? Isn’t it better than having a penis that looks like it eats Jedi’s?”
“I suppose so, but foreskin actually increases the amount of pleasure” he shrugged his shoulders “I don’t know. I just sure as hell know that our kids are getting it cut off.”
“Damn right they are! I want the best for our children.”
“Me too, they’ll even fit in better. It’s the most important thing you can do for a child.”
