It is generally accepted that the most normal method of masturbating, is by moving the foreskin. With these conditions a freely movable foreskin at the same time as a full erection is impossible. This lack of freedom of movement is similar to a man who is fully circumcised, but whereas the latter is limited, he is not constrained. Masturbation occurs throughout puberty previous to any relationship. It could be argued that a male's ability to develop a relaxed relationship with his body and his manhood is based on feeling himself and especially masturbation.
People avoid pain and difficulty.
With this blind spot, any re-education is difficult. The carrier is not as aware of himself and he is probably not as interested generally in pictures, information or education about the male phallus. This anatomical inhibition functions in a similar manner to the generally understood emotional inhibition. Anyone with any sort of inhibition does not experiment as freely in that area, he does not discover, he is simply not as aware of the area. Letters I have received show that any seed of awareness may be simply repressed.
