Another flaw in the study is that it only relates to pleasure as experienced by men. Where are the studies into the comparative pleasure felt by women with circumsized and uncirsumsized men?
I am not circumsized, and Ive frequently dealt with two reactions from women:
1) An initial scepticism, as among American women my age (I am 34) I am typically the first uncircumsized male theyve been with, and then
2) This scepticism usually turns into enthusiasm. Once the unfamiliarity fades, most of my partners have told me they prefer my "natural" penis. Of course, this could just be polite pillow talk, but the frequency of the reaction leads me to believe there's truth there.
Intuitively, it makes sense to me, since uncircumsized sex by its nature entails less friction (which is probably why foreskins exist in the first place).
