About its purpose in Judaism, here's what Maimonides wrote:
"[W]ith regard to circumcision, one of the reasons for it is, in my opinion, the wish to bring about a decrease in sexual intercourse and a weakening of the organ in question, so that this activity be diminished and the organ be in as quiet a state as possible. [...] How can natural things be defective so that they need to be perfected from outside, all the more because we know how useful the foreskin is for that member? [...] The bodily pain caused to that member is the real purpose of circumcision. [...] The Sages, may their memory be blessed, have explicitly stated: "It is hard for a woman with whom an uncircumcised man has had sexual intercourse to separate from him." In my opinion this is the strongest of the reasons for circumcision."
The words of Kellogg, the man behind much of its popularization in the US:
"A remedy which is almost always successful in small boys is circumcision, especially when there is any degree of phimosis. The operation should be performed by a surgeon without administering an anæsthetic, as the brief pain attending the operation will have a salutary effect upon the mind, especially if it be connected with the idea of punishment... In females, the author has found the application of pure carbolic acid to the clitoris an excellent means of allaying the abnormal excitement."
