Op I think you're being very funny!
Fwiw I went out with a circumcised man, and he hated his parents for mutilating him. He was a surgeon and just couldn't get his head around the fact that his parents had made him have unnecessary surgery when he was a baby.
Culturally not many boys are mutilated in the UK, do you really want your boys to stick out like sore thumbs while all their teammates and loo mates are entire, and unmutilated?
Do you really want your little fellows to be the odd ones out, or just feel they fit in with members religious groups who ritualistically chop bits off?
Do you want a good relationship with your boys in the future?
I would urge you to think about this carefully, more carefully than you do now.
You maybe see circumsision as a way of helping him fit in to your family.
Do you only seeing your boys as a part of a family unit? that they will form a sports team of two and only go to have a wee together, and no one else will see their chopped willies, and no one will ever make fun of them? Or notice and judge them, and you?
By making them fit into the family unit together, you may be excluding them from their wider social units later, and they may hate you for it like my friend hated his parents.
