To Carang (with respect to female circumcision).
Well, for your info, female circumcision and male circumcision are completely different things. if you want to compare the 2, then lets just say that female circumcision (which is usually followed by suturing of the skin surrounding the outer lips which have been cut off as well in some cases to only leave space for pee and menstrual blood...no space for a penis which will have to tear its way in on wedding night) would be the same as the complete removal of the penis up to the scrotum...now this is not the same at all as only removal of the foreskin, which will not cause any harm or pleasure removal during intercourse!
The foreskin use is as a protection for the head of the penis and is used as "lubricant" during intercourse. The problem with having the foreskin is that it needs special cleaning attention. If good hygiene is not respected, infections will occur.
It is proven that women with circumcised partners have a much lesser chance of getting cervical cancer (caused by Papilloma virus).
In some cases the foreskin cannot completely retract itself, inducing pain, impossibility for sexual intercourse, and infections. Then, circumcision needs to be done.
I am not saying that doing it to a baby will not cause any pain, but the pain is not remembered (I have asked several Jewish friends). As for that child being less pain resistant...this is a personal behavior and not linked to previous pain endurance.
It was a standard trend in the US, but it has been stopped in may states in the past few years.
As for sexual intercourse, having a circumcised partner makes lubrication solely the affair of the woman...no foreskin to act as "lubricant". But then again, KY does exist, and some women with non-circumcised partners still have lubrication problems...so really, having your child circumcised or not is your own personal choice. He will have a happy life and he will enjoy his sexual life as much as any other man.
