The Interrogator

When Robert is incarcerated while on vacation in Thailand, he's interrogated for a crime he did not commit. The experience revives an adolescent affliction - Robert can "get it up", but he cannot "get off". He gets NO climactic sexual relief!
Later in NYC, he encounters the same female who interrogated him in Thailand, a Psych professor specializing in sexual behavior. She assures Robert that she can cure him of his terrible affliction, but does he dare risk more interrogation? Can the methods that caused his condition actually cure it?
