Something like 9/10 in my age group and region are circumcised.
I grew up knowing I had something special about me for good (feels good to the touch) and bad (risk of being razzed for the difference).
I'm at the point now that I don't think much about it. I don't walk around wondering who's circumcised or not. I just know I'm very lucky and so is any girl who has sex with me.
I did have an experience that jarred me a bit, though. I went to a spa in Europe (with my ex) where everybody enjoyed the hot water and steam and such, fully naked. No sex, of course. Just adults at an indoor hot spring.
This being Europe, there were foreskins on every male. Except one, who I guess was also a tourist.
And for the first time in my life, I didn't feel so special.
My ex still made the experience fantastic when, back at the hotel, she worshiped my foreskin for a good hour.
Yet, I think I'd like to have that casual-nude experience here in the U.S., just as a visual reminder of how lucky I was to be spared the cut.
