on't do it! 
I am actually turned off by uncut c^cks. They remind me of a dog's penis for some reason 
Thank god, most of my clients are cut. But to each their own. Some may find cut unattractive. But growing up with a housefull of males, you get use to seeing one type of penis. My very first encounter with someone who was not cut, was actually being in this business a couple of years ago, and a very bad one: he dripped, and it smelled very very bad. Eversince then, I dread the uncut, but have gone through the appointments anyways. But, whenever I encounter a drippy drip and unclean uncut c^ck, I always make sure he taken immediately into shower and extra time is added on the our session to make sure that he is thoroughly clean.
As for kids, if I do have a son one day, he surely will be circumsized. I have spoken to many civi's and provider girlfriends, and they had shared the same point of view. Also, just because a lady does not speak up about her preferences, doesn't mean that it's not there: it's just not spoken. Most men don't know how I feel about uncut, but some do.

I was getting ready to enroll you in a course on English comprehension in the School of Continuing Education.

BTW, I too have an opinion on this subject, but since I'm not a doctor, I wouldn't dream of offering reasons to "do or not to do."

... "Who gives a shit?"
Well, the original poster, I guess. He asked the question because he's worried about his son. So, I'll reply in some detail, to the best of my ability. If you don't want to read it, please pass by now.
You also asked:
"How does anyone know this? How do you test for this?"
Here's the best answer I can give.
The best test must be by way of those adults who, for one reason or another, have been circumcised later in life, as they have personal experience of the comparison. One such is a poster above going by the alias of "FormerBaloneyDick" and if you read his post you will see that he prefers to be circumcised. However, as he was feeling pain and was unable to have intercourse uncircumcised, that's no surprise. A small percentage of men will require circumcision for medical reasons. You will note that he admits to a loss of a degree of sensitivity since circumcision.
I have also read a number of contrary accounts, and here's an example:
"Getting circumcised was the most foolish thing I've done in my life. I had it done when I was 27.
It 's now been three full years since this grave mistake was made. Having grown up in the U.S., as hard as it is to admit, I got circumcised purely out of curiosity, as the subject had been so close to the top of my mind for all my life.
"I was quite sexually active before marriage, and had a pretty normal sex life after marriage for two years before my reduction. Now I am essentially only interested in oral sex, as vaginal sex does not provide the detailed sensations that it did when I had a foreskin. The last thing a foreskin is - is a hindrance to sex. The analogy of "seeing without color" is perfectly apt to describe sex without a foreskin. Rather than being a touch-sensitive organ, it becomes merely a pressure-sensitive tool. BIG DIFFERENCE!"
This is just one of a number of comments set out here at:
http://www.mothersagainstcirc.org/sex-cut-uncut.htm
This is an anti-circumcision site but if you scroll down the page and read the comments by adults who were cut later in life, there are a number of anecdotal stories both for and against, and there does seem to be at least a modicum of balance in the information provided.
For a clinical explanation about the mechanics, hows, whys and wherefors:
http://www.cirp.org/pages/anat/
from which the following is an extract, which should explain why there is more sensitivity with a foreskin.
"Following circumcision, the foreskin of the penis has been cut away. The surface of the glans has developed a thick, dry layer of keratin (toughened skin), which makes it less sensitive to unwanted stimulation, but also less sensitive to the more subtle qualities of lovemaking.
"The gliding mechanism
During intercourse the loose skin of the intact penis slides up and down the shaft of the penis, stimulating the glans and the sensitive erogenous receptors of the foreskin itself. On the outstroke the glans is partially or completely engulfed by the foreskin. This is known as the `gliding mechanism.'
"The gliding mechanism is Nature's intended mechanism of intercourse. As such, it contributes greatly to sexual pleasure. Also, since more of the loose skin of the penis remains inside the vagina, the woman's natural lubrication is not drawn out to evaporate to a great extent, which makes sex easier without using artificial lubricants.
"... When unfolded, the prepuce is large enough to cover the length and circumference of the erect penis and acts as a natural sheath through which the shaft glides during coitus. Only the presence and functions of the prepuce allow for physiologically normal coitus to occur as designed by nature."
Basically, it's there for a reason. There's nothing you can do about yours if it's gone, but I don't think it's a bad thing for anyone who is taking this step for their child to do so without being properly informed. But by all means, the original poster should rely on expert opinion, not mine.
