There have been several studies evaluating post surgical problems of adult circumcision. They have quantified a high incidence of impotency associated with the surgery. My own conclusion is that the circumcisions have resulted in a reduced level of sensitivity that is subconsciously not acceptable to the men. Men circumcised as infants would have this same level of insensitivity but being circumcised all their lives, they have not experienced the normal level of sensitivity and do not have the post surgical letdown. Further evidence of this is men who were circumcised as infants having a much higher resistance to using condoms than intact men. Condoms reduce the sensations of sex and the conclusion is that the experience is reduced for circumcised men below an acceptable level. It would be like putting on two condoms, one over the other.
