I've still been having a hard time talking about it, but I just posted the question here because I found it really puzzling that after he took advantage of me, he preached at me.
It wasn't a stupid question Sequoia, there are a lot of weird cults that combine preaching at people with strange sexual practises. I have a friend whose former partner was in The Family also known as the Children of God who was raped in the cult and had a miscarriage after getting pregnant. She spent many years in a psychiatric hospital afterwards. They had communes where they practised child sex in the early days but that's now banned. They did recruit people through 'flirty fishing'.
So asking if JWs allow this behaviour is not so strange given the history of religious cults. I'm glad you've reported him and are going to talk to your counsellor about this horrible incident. Take care.
