I have read this book cover to cover though not in a long time. I'm writing this review, because this is the book that justified male genital cutting with the false information that there is no difference between the sensitivity of the circumcised and intact penis. The falsehood was implicit, they never considered the foreskin itself, despite the fact that the inside of the foreskin contains the three most sensitive parts of the penis! Circumcision actually reduces sexual sensitivity by 75%, and it took 40 years for the medical literature to substantiate that fact (Sorrells, 2007). The false information from this book is repeated on the Wikipedia article on circumcision. Even today most doctors do not have the updated information yet! It appears that circumcised (and circumcising) doctors do not want the real information because it makes male circumcision obviously appear to be the massively desensitizing and harmful procedure that it is, and they could not afford to be held liable for all the damage they caused or facilitated.
In America, we see the damage from male circumcision manifested as higher incidence of female arousal disorder. It's not that American women are less aroused, it's that the circumcised penis extracts lubrication from the vagina much more than the intact penis does. Circumcised men also exhibit orgasm difficulties much more often (premature ejaculation is less common but possible, but the most common side effect is difficult or delayed orgasm). Circumcision is cutting decades off American men's sex lives by reducing the sensitivity of the penis. Sensitivity decreases naturally with age. Once penile sensitivity is very low, men experience erectile dysfunction (Rowland, 1998). Infant circumcision without a dire medical reason is incredibly harmful.
