What a wicked case. How could he get through with this for so many years? I mean, the guy simply masturbated the girls and they kind of should have noticed that..

But what I really do wonder about is whether it actually helped them. From an ethical perspective it is out of the question that he committed crimes, but from a medical one? After all, masturbating women actually used to be a medical procedure that was supposed to calm them down (and it kind of does..). Even vibrators have been invented as medical instruments to serve this purpose. And at the end of the day, he belonged to the medical staff for a lot of years. Either he was a really good conman - well, or he was competent and the girls had good performances.
