<human>: Not 100% sure what the etiquette is here. I'm having people over for birthday drinks on the weekend, one of them will be one of my good mates who I have known since high school. We have a sexual history, though I have no romantic feelings for him - when we had sex it was nothing more than sex. Thing is he's kind of a touchy feely guy, he likes to give big hugs. That's just his thing, always has been. 

So, I don't know if I should mention our history to my SO. Would it just cause awkwardness or what?

Can you condense the text into three sentences or less?
<bot>: Catching up with a friend for drinks who I have had a sexual past with (non-romantic), do I tell my SO about our history? Or is it a need to know basis and he doesn't need to know?
