Being uncut in american is slightly more uncommon now and when your sons are men will be even more so, you can easily tell a woman what to do with a foreskin...
Circumcision has been more common on the West Coast and among medical professionals (talking about America) for the last few generations. The last I read, those with circumcized penes were less susceptible to infections in the area (which were promoted by poor hygiene when men didn't adequately clean under the foreskin).
I really can't understand how men can make value judgements about sensitivity. The only men who could possibly know are those who had circumcision as adults for a before-and-after comparison (preferably with a polyplethysmograph). I know they are called "lie detectors", but I really want it for getting a hard copy of the stimulation levels. Even then, I am less sensitive to stimulation
now than when I was
in my teens. Whether that is due to being jaded or, more likely, lower testosterone levels as we age is up to debate, but how can you adjust for that?
I certainly have no scarring on the head which interferes with sensation. The complaints that being circumcized damages the head and that you might as well rub sandpaper on it seem specious; I mean, really, where do you buy your underwear?
I still encounter skilled fellatrixes from time to time who can make me come when they choose, but most women just put it in their mouths and move their heads and tongues a little, with no real understanding of what they are doing (or no intent). Can't really blame that on being circumcized.
