I remember serving on a JC that was considering the reinstatement of a sister who had been disfellowshipped by another congregation's JC. We noted her repentant attitude and recommended that she be reinstated. Afterward she thanked our JC for not requesting that she explain all the gory details about the sexual act that caused the other JC to DF her.
Being aware that some JCs went too far in their request for intimate details of "sexual wrongdoing," any JC that I served on I made sure that such questions were not asked of the person. What do these details have to do with the person's repentence? However, there were elders who got their jollys off asking such intimate questions.
