Do hotwives ever tell friends?

My wife is getting so close to making my fantasy of her being a Hotwife a reality. Clifffsnotes version for context: she’s all of sudden more open to talking about fucking another man, and she brings it up more than I do. The focus has been on a builder working in our house, and she has stepped up to open flirting, chatting with him not wearing a bra, talking about his love life. On Saturday he was working and she spent a few hours as it turned out simultaneously teasing both us. We’ve moved from joking about to whispering about it to just talking, and I’ve encouraged her. Yesterday we were talking about the situation. I asked her put eight if she wants to fuck him and she was coy; said it might be weird bc of the professional relationship. I asked her if she told her best friend about my kink. She replied “that you want me to fuck other men? Or that you maybe want to watch me fuck other men? No! It’s weird to others. You’re not weird, but it would seem weird.” Do others feel this way? Why is there a stigma attached to this kink—-it seems more acceptable to be a furry! Do hotwives mostly keep it from friends bc of a social stigma? Most importantly, if she thinks it’s weird to vanilla folks, then is that a stumbling block to her just embracing her inner sexy self and fucking this guy? How long can she hang around him, flushed, big tits on display, before she just relieves the tension for all three of us.
