Perhaps so, but that may be a result of the circumcised penis having more exposure to chaffing over time.
Does it really matter why? The study also shows that the glans of both kinds is the
least sensitive part of the penis.
The penis is more than just the glans,
....and even more so when it hasn't had anything cut off. Go to the second link, look at the graph, see the lonely red (intact penis) short (sensitive) bars for the parts that the circumcised man doesn't have.
and the millions of circumcised men in the world have hardly diminished their sexual activity
Fucking more, but enjoying it less?
nor are complaining about issues of tactile sensitivity.
Does a colourblind person complain about not being able to see colour?
Let's introduce another recent study that finds that circumcision significantly reduces the rate of HIV infection.
Introduce? Where have you been? It's been debated to death here.
It's been conventional, though debatable, wisdom that circumcision helps to reduce disease. I would much rather deal with a minor

loss of sensitivity in the glans than be put at greater risk for sexual complications.
IE, let's talk about something else. OK, let's: All those claims of disease prevention have proved to be exaggerated or totally bogus. Just look how circumcision goes from disease to disease, looking for the most frightening of the day ( like a child in a party shop before Halloween). In the late 19th century when people worried about retaining their bodily essences, it was "moral hygiene" (ie masturbation). Then after WW1 when men were coming back from the brothels of France with syphilis it was "VD". Then when people (especially women) took up smoking, and cancer was the great terror, it was cancer. After WW2 it was "in case he has to fight in the desert" and (because most men were now circumcised) "to look like dad". Then when those were flagging, Urinary Tract Infections were wheeled up (which had the advantage of happening to babies, and so justifying doing it to babies - never mind that 4 times as many girls as boys get UTIs). So it was inevitable that HIV should take its turn. (Maybe, just maybe, circumcision does cause a measurable reduction in woman-to-man heterosexual transmission of HIV, but that's a poor reason to do it to babies in the US.) And each time a new disease comes along, the others are pretty much forgotten. It's as though appendicectomy were touted as being good for stomach ulcers, then rectal cancer, then brain tumours, then carpal tunnel syndrome.
