How to tell husband about wifesharing fantasy

I was wondering if anyone could give me advice about how to talk to my husband about wife sharing? I wish I could bring it up to him without scaring him. If he wasn’t into it, I would just give up the idea and not mention it anymore, it’s not worth risking it.

Sarah: no, we don’t watch porn together. I’ve never once seen my husband even watch porn, although I do, in secret. That does sound like a good idea although I’ve talked to him about watching porn together and we ended up deciding not to.
