Conclusion
"Mary, in my opinion, your problem can be treated quite conventionally. Your father still loves you. His actions that night were caused in a state of mild insanity, by a number of various causes. It does happen, and not rarely either. The way for you to be cured of your present frigidity is through honest analysis and therapy.
"Now I want you to come see me once a week. I want you to examine your mind for questions and explanations. Truth is what will remove the frustrations and the guilt. When you've progressed sufficiently, I'll maybe bring your father to the sessions also.
"That you were able to forgive him later on is a giant step in the right direction. It shows there are no severe emotional scars. Also, that you were able to achieve that climax under those extraordinary conditions is a definite positive omen. As you mature, and get to trust in a man, your body will learn to respond physically in a normal way."
