If he did undergo this "ordeal" in 1924, then we must presume that his key associates of that time -- including Nellie and Pauline -- functioned as his assistants.
There is no reason nor evidence to suggest that *everyone* around Crowley was involved in having sex with him. I grant you that it would take a er, "special" type of person to befriend him, but that doesn't mean EVERYONE was having sex with him - I know some were, but there is no reason to believe the "assistants" had to be Pauline.
