DEAR DEIDRE: I SPOTTED my sister at an orgy and now things are weird between us.
I’m 40 and my wife is 38. We have an open relationship and regularly attend sex parties.

We missed them during lockdown but now they are happening again.
Last month, my wife and I went to an event with a few of our swinger friends.
About halfway through the evening, I walked into a room and saw a very attractive woman enjoying sex with two men.
To my horror, I realised the woman was my sister, who is 36. I’m not sure if she saw me.

I ran out of the room, found my wife and we went straight home. But I haven’t spoken to my sister since.
I don’t know how I’ll ever be able to look her in the eye again.

DEIDRE SAYS: Many of our sexual tastes are often informed by childhood, so perhaps it’s not so surprising that your sister shares the interest in sex parties.
You could pretend you didn’t see her, and try to act normally with her.
But if this is bothering you, maybe you need to say something. Why not send her a message and meet for a drink to talk it over?
Your relationship is too important to put at risk over this.
Also, make sure you are not taking risks with your health. My leaflet on Satisfying Safe Sex explains more.
