Have you ever overheard a conversation discussing your wife/partner in a sexual way?

Or have you ever participated in a conversation discussing your wife/partner in a sexual way?

My best example is when I uploaded a few pics to Facebook (or so I thought) and shortly afterwards received an email thanking me for sharing the pics of my wife. It turns out I posted a lot more that I had intended. Mostly regular pics but a few that were taken "for my own pleasure". Nothing porno but.....you know what I mean....lol

What was interesting was that he emailed me to my regular email account, so he was somebody who knew me. And knew my wife and had very clear ideas of what he would like to do with her....
