Respectfully, this is a case where a lack of "field experience" combines with asking AI about peepees, and it gets weird after that.
Like another commenter said, this is a small (62) group of men tested for stimuli that don't appear to resemble sex.
To be blunt, I think it is apparent to those with experience that uncircumcised penises are significantly more sensitive than circumcised ones. If you wanted to test this - get a big sample size and simulate the 3 common types of copulation in a standard way (lol).
