Circumcision is bertter than uncircumcision
Being circumcised in infancy is like being born with a condom on you that stays there 24 hours a day for life:
"Male circumcision reduces the risk that a man will acquire HIV from an infected female partner, and also lowers the risk of other STDs, penile cancer, and infant urinary tract infection. In female partners, it reduces the risk of cervical cancer, genital ulceration, bacterial vaginosis, trichomoniasis, and HPV."
According to the same authoritative source:
"Well-designed studies of sexual sensation and function in relation to male circumcision are few, and the results present a mixed picture. Taken as a whole, the studies suggest that some decrease in sensitivity of the glans to fine touch can occur following circumcision [48]. However, several studies conducted among men after adult circumcision suggest that few men report their sexual functioning is worse after circumcision; most report either improvement or no change [49-52]. The three African trials found high levels of satisfaction among the men after circumcision [16, 17, 18, 46]."

Even if circumcised guys have less sensitivity, that does not equate to less sexual pleasure or shorter durations of intercourse. When I haven't cum for a few days I am much more sensitive than when I've cum 2 hours ago. In the former case, due to having greater sensation, it is much harder for me to last as long as in the latter case. If a guy with half as much sensation lasts 10 times as long as the guy with twice as much sensation, his overall pleasure should be 5 times as much as the guy experiencing twice as much pleasure at any moment. Moreover, this does not even consider the pleasures of sex enjoyed in other areas of the body, and that of one's partner. Many women prefer a guy who can last longer.
