<human>: To start off, I will say I am a pretty sexual person and have had a fair number of casual sexual partners, some of whom are good friends of mine. most of These casual relationships had absolutely no emotional aspects to them. 

My SO knows my friends, thought not well, but recently we have been seeing them more and he and they have been bonding a bit more. One friend in particular who I'll call Larry has been very friendly and seems genuinely interesting in befriending my SO. Larry and I had a casual hookup thing going on right before I started dating my SO. I don't think it's necessary to bring it up since I have zero romantic interest in Larry and it ended a while ago. I still consider him a good friend and there are no issues between us because of our sexual history. 

My question is, is it worth it or even a good idea to bring it up to my SO? If they become friends I don't want him to find out and feel slighted in anyway... I guess I'm thinking into the future at it perhaps causing problems (though I don't think my bf would hold a grudge about it as we are very open and honest about everything). I don't want to be lying by omission or anything...

Could you distill the essence of the text into 1-3 sentences?
