There is a book about this topic called "Sex as nature intended it." I haven't read it yet, but plan to soon. Here is some info about it that I copied from the above linked forum:

Great new book reveals the benefits of being INTACT.

"Sex As Nature Intended It." This is the *first* book to detail the many sexual functions and benefits of the male foreskin for both the man and his female partner. It presents unequivocal evidence that the foreskin plays a definite, delicate, vital role during intercourse, that not only promotes increased sexual pleasure, but this enhanced pleasure also serves to enrich and continually re-cement the love bond, borne from sexual union.
Circumcision´s removal of the foreskin -- ultra-erogenous tissue and the penis´s only moving part -- not only diminishes the man´s sexual
pleasure, but also the woman´s.
A national survey of women, conducted by the author, reveals that circumcision abnormalizes the way the penis thrusts and feels to a woman, and significantly diminishes her sexual enjoyment and her ability to achieve orgasm from intercourse. The book´s explanation of the profound negative effect circumcision has on the intercourse experience of both partners will surely leave America stunned. But luckily, there is a bright side to this shocking news. It is now
possible to restore the foreskin through various non-surgical techniques. In the course of addressing this topic, the book enwraps the emerging foreskin restoration movement with hope, promise, and dignity. I found the book captivating to read and very informative. It conveys a powerful message that is destined to capture our national consciousness. I recommend it very highly.
