I agree with everything but have found adult clubs a helpful way of easing them into being fucked by other guys.
I explained it was a sexy ambience, she could dress up extra sexy but would not have to do anythinbg she didn't want to do. No means no so she can say no when a guy approaches her and there are security guys around to keep people safe.
This gave her peace of mind to try it - our first visit I told her to just look around and see how it worked - she chatted to girls to get their take on it and found it was more "normal" than she imagined and she enjoyed the ambience.
It took quite a few visits before my present wife went to the sex room with a guy but patience worked, letting her go at her own pace but putting her in a sexy but safe environment helped move her on.
