Dr. Rajan give us an insight into the Kali-br mind: Structure Vol II, P. 561.
"Delusion: impression of danger from his own family". This means that the feeling is that those you depend on (Kali) will harm you (Brom).
In that situation you have to be careful to conform to your parents wishes or you get punished swiftly and harshly. You end up thinking even a small mistake is a crime, "Delusion, crime: committed he had".
Sex becomes riddled with guilt, and since any sense of normality or morality is eroded, perversions arise.
