Circumcision amputates the most erogenous part of the penis. It is a partial castration but such that does not impair insemination and fertility. Removal of the foreskin triggers the Circumcision complex while according to the Freudian psychoanalysis the fear of removal of the penis initiates the castration complex.
The anatomical analogy between castration and circumcision gives us reasons to assume that they have analogous psychological effects. As far as circumcision supresses sexuality it may be regarded as a partial castration. The Circumcision and castration complexes must show great similarity because both of them cause sexual frustration.
