It's just important to recognize that there are reasons beyond religious ones why the practice continues. One reason is cosmetic. In countries where it is dominant, some parents simply want their child to fit the norm. To be honest, I found the teeth I had pulled, braces, and other orthodontic procedures I had as a child to be infinitely more scarring than my circumcision. (I say infinitely, because I can't remember my circumcision at all.) And, those painful orthodontic procedures were by and large done for cosmetic reasons. If most people let their teeth go crooked, but one religious group didn't, we would have to call religious childhood orthodontics barbaric too.
If people consider an uncircumcised penis to be as socially negative as crooked teeth, then IMO it would be very difficult to justify being ok with one and not the other. And what is more, preventing crooked teeth can easily be a more painful process. I'm curious about this. Can't really search at work, but if you can point to one, I'd like to see. I think sex is pretty great. I'd hate to think it could have been even better. And I'm not even Jewish! :)There have also been studies that show that an in-tact penis provides more pleasure to both the man and the woman during sex.
- Circumcised males may also be at risk of premature ejaculation, or alternatively may have to resort to prolonged thrusting during intercourse in order to stimulate sufficiently the residual erogenous penile nerve endings to trigger ejaculation (Bensley & Boyle, 2001). They report that the unnatural dryness of their circumcised penis often makes coitus painful, resulting in chafing and/or skin abrasions (Gemmell & Boyle, 2001). Concomitantly, O'Hara and O'Hara (1999) found that female partners reported significantly greater sexual pleasure from intercourse with genitally intact men as compared with circumcised men. Money and Davison (1983) had previously documented a loss of stretch receptors in the prepuce and frenulum and an associated diminution in sexual response, thereby restricting a circumcised man’s ability to achieve arousal. Consequently, erectile dysfunction may be a complication of male circumcision (Glover, 1929; Ozkara, Asicioglu, Alici, Akkus, & Hattat, 1999; Palmer & Link, 1979; Stief, Thon, Djamilian, Allhoff, & Jonas, 1992; Stinson, 1973).
