Hi Leanne. First off, I'd be very disappointed if my son ever married someone as ignorant and uncaring as your cousin's wife. If you love someone you love every part of them no matter if it's your idea of "perfection." And someone so disgusted at a natural, normal body part is ignorant, plain and simple.
Honestly, if my son ever wanted a circumcision for vanity reasons I'd be saddened, but I truly doubt that would ever happen. I plan to educate him on why we left him intact and what circumcision is and I plan to remind him of it -- of course keeping what I tell him appropriate for his age level. I think once he learns all that circumcised boys are missing, he would never want a circumcision.
If a doctor ever prescribes a circumcision, we will keep in mind that many American doctors are ignorant on the foreskin and not only look for a second opinion but try other options first, depending on what the problem is. We would treat any problem with his genitals with surgery as a last option just like we would with a daughter. Since the non-infant circ rate is incredibly low, with a portion of those circs being for vanity reasons, I would say the change of a TRULY medically necessary circ being almost nil.
And like Frank says, if my son ever really wants or needs a circumcision he can get one. A circumcised man is !@#$ out of luck, if you know what I mean. He can go through the long process of restoration, but never totally gets back what was lost.
And Frank, just to clarify, you mean an adult circ is almost painless, because they can get proper anesthesia, correct? Infant circ is very painful even with anesthesia because it just cannot be adequate (I know you know that Frank, just throwing that out there in case someone is reading who doesn't know!).
