He also warned that it is "hard for a woman with whom an uncircumcised man has had sexual intercourse to separate from him."
A 13th-century French disciple of Maimonides, Isaac ben Yediah claimed that circumcision was an effective way of reducing a woman's sexual desire. With a non-circumcised man, he said, she always orgasms first and so her sexual appetite is never fulfilled, but with a circumcised man she receives no pleasure and hardly ever orgasms "because of the great heat and fire burning in her."
