I just remembered my mother-in-law bringing up circumcision when my wife was pregnant with our first son.
She was visiting, I think reading an article on pregnancy or something, while I worked on the computer on the other side of the room. Wife was sitting on the couch with her. (My father-in-law and brother-in-law were circumcised at birth.)
MIL said something about circumcision's benefits, then asked my wife what our plans were. Wife responded:
"Intact's not [circumcised]."
The room fell silent as MIL realized her daughter had been having sex with an uncircumcised man for almost a decade. I like to imagine she was thinking what I was thinking -- all the enthusiastic blowjobs, the whispering "I'm soooo glad you're intact" during foreplay.
And nothing more was said. AFAIK she never brought it up with my wife again.
A few weeks later, it became obvious the word had spread among the in-laws. Wife reported that her brother raised circumcision with her during a visit, claiming our son would "never get laid" if he had a foreskin. I wonder what she said in reply, or if he realized the stupidity of saying that to the wife of an intact man.
Later, our son was born and diagnosed with chordee, a curvature of the penis blamed on poor development in the womb. Urologists' only solution is to circumcise, then use the foreskin to patch the underside of the penis. I do not know how this would help the underlying tissue (urethra, penile body) to lengthen. His penis didn't look abnormal to us.
This got FIL interested, and he sided with the pediatric urologist's opinion that we undertake plastic surgery right away. FIL also took the opportunity to add that uncircumcised boys are subject to locker-room abuse -- another thoughtless thing to say to a woman married to an intact man who grew up in the U.S.
(Conclusion: We got my son an appointment with foreskin expert Dr. Paul Fleiss (R.I.P.) promptly. He said if this was chordee, it was a mild case, and furthermore, there was no way to predict how an infant's body parts will grow on their own. He advised wait-and-see, and he was correct. Teenage son has a healthy, normal penis today.)
