You are now on the road to answering your own question. I am SO glad you told someone!
That p. was a sick, sadistic man who violated your trust, your rights, your very body and mind by taking advantage of your vulnerability. I doubt you were the first or last, hopefully he was caught at some time and put out of business, but even if not----NOT YOUR FAULT, Not your responsibility.
I have kept silent about things to protect my own "image" of myself as someone who can be in control; so of course it would be my "fault" when something happened. Especially since, there were times I was able to be assertive, strong, able to defend myself, and I would think "well, you didn't that time so you must have wanted..." instead of realizing there were times I was Very vulnerable and that was probably the reason I needed to believe I was a person IN Control.
