You can't make that claim without proof. You have uncut guys who dont get satisfaction as well as cut guys. Its an individual mechanism if you ask me. Myself after being cut I didnt lose any sexual sensitivity.
This is actually part of the reason why I'm against circumcision of people who can't consent to it. An individual should be permitted to make the decision for themselves, as they are the absolute best people to decide whether or not their foreskin contributes meaningfully to their sexual pleasure. There are many intact men that say they love their foreskins, it is their favorite part, and they can't imagine sex/masturbation without it. If they are wired so they're foreskin is more necessary for sexual pleasure, how would they have been affected by its removal?
BTW, did you see the last study I posted about circumcision, the one in China? It actually provided a great explanation for why some men might experience the effects of circumcision much differently, even though that wasn't the purpose of the study.
The ONLY thing that changes is the mechanics. Rolling skin versus no rolling skin. Does that automatically equate to better feeling. Not necessarily. I see your point and I would tend to agree but I feel that it is polarizing to basically say a cut penis is inadequate, or heck even tell yourself it is inadequate having never experienced it for yourself (I'm not saying go out and get circumcised, all Im saying is that there are many men happy with their circumcision. Heck some of us myself included wished that it was done as a child).
Well, let me set the record straight by saying I don't think that every circumcised penis is automatically inadequete. In fact, I have agreed that in many cases, it may be a matter of preference. If people are happy with their own circumcised penis, I encourage them to be happy with their own circumcised penis. However, most of the reasons given boil down to "I think it is more appealing that way", a valid stance, but not a reason to pursue the operation for anyone else. With that in mind, I don't think the choice should be stripped from an individual before they are old enough to make it for themselves. The effects of circumcision, given that there are people on both extremes, can be said to be uncertain
at best in regards to sexual sensitivity. In return, for the risk that they could lose a great deal, what is the child being subjected to the procedure receiving? What is our justification for denying them so personal a choice? If we are left without any reasons for the child's well-being, what reasons are left besides our own vanity?
But to answer the OPs question there is really only ONE dominating reason why Circumcision is prevalent in America: When covered by health care/insurance, circumcision rates are high, look at the demographics on the states that cover it, Not a single one below 70%.
We may not see eye to eye on most to do with circumcision, but I agree with you 100% here. If people look at the details they might see circumcision is unnecessary, but if the doctor recommends it and the procedure is free to them...
I think that honestly this would be a valid fix, not perfect but reasonable. Just declare that non-medical circumcision can't be covered by insurance as a medical procedure. See how tightly people cling to their "parental rights" when they have to shell out the 300-400 dollars cost for a procedure the doctor tells them their baby doesn't need.
