I am curious about the methods used - my reading of this is that is inconclusive. It sounds like the question was o"on a scale of 1 to 10 how pleasurable or painful is this?" Assuming these men have had sex, which is probably a ten for them, it isn't at all surprising that they would find having a warm wand or some prodding with a wire about as pleasurable between cut and uncut dudes. They compare it to their 10, and presumably most actions suck compared to that. Tactile heat and sensitivity are fine, but the pressure corpuscles on the foreskin are the argument for it, and warmth and running a wire over it measure part of that. And nothing seems to have gone for deep pressure on the penis.
I still haven't read a scientific study with a realistic comparison. This does not appear to be one.
"
The scientists tested the men for tactile and heat sensitivity of the penis at four points: the midline shaft, the area next to the midline, the glans and, for the uncircumcised, the foreskin. As a control, they also tested a site on the inside of the forearm.
Uncircumcised and circumcised men did not differ in sensitivity to touch or temperature at any of the four sites tested, and sensitivity at the forearm was lower than any penile site for both groups.
While pain thresholds at the foreskin did not significantly differ from any other site, the foreskin was more sensitive to temperature detection than the glans but less sensitive than the shaft.

Circumcised dudes - you love your penis, and so do I, this isn't a judgment.
I'm fascinated by this topic and the differences in pleasure we feel. This study appears to me to have been constructed by an idiot - why would you not measure tactile sensitivity at the circumcision scar, and why would you look at heat sensitivity which is irrelevant to sexual pleasure.
It seems self-evident that cutting off one of the two most sensitive parts of the penis (glans and foreskin) will reduce overall pleasure for the foreskin owner. Having lost the foreskin already (many of you americans) - enjoy what you have and move on(or restore if you will). Good luck.
