On a spiritual level, it's said that circumcision breaks the psychic bond between the man and the woman during intercourse where the lack of full sensation or sensitivity causes mental distress or mental discomfort for both partners, preventing them to merge into one single being of energy that the sexual relation creates, making impossible or almost impossible for both to make a connection to reach and to know... God (Nature, God, Universe, etc.), through the act of procreation or through the mere act of pleasure... sex.

When this full pleasure cannot be achieved, all sorts of problems arise between man and woman, therefore, they can be divided to avoid them to act as one single being of love, and they can be to some extent manipulated, misguided, corrupted and cannot act like a full one hundred percent being of love like it was intended. Of course, it doesn't happen in all the cases, but in the majority does happen.
