<human>: Right, so I'm in a fresh relationship (dating for a month, just recently got together). So far he has not seemed interested in talking about past sexual experiences, which I don't mind. 

The thing is, on a regular basis I hang out with a couple of friends that I used to either date, be fuck buddies with or at least have slept with. He knows about one because that's his friend too, but not to what extent - he only knows we slept together once and only because it was at a party and he was there. This was right before we started dating. He has not made any attempts at all to talk about this, which again is fine by me but still feels a little odd. 

However, I feel like I would be lying or atleast decieving him in some way if I went to hang out with one of these friends one on one without him knowing that I've slept with them before. Do I tell him or should I just let it be? If I do tell him, how do I go about it in a tactful way?

If it makes any difference, details: the fuck buddy was years ago, like 3, and now there's no sexual tension whatsoever. The guy I used to date (that is also his friend) I went on a couple of dates with like 5 years ago but we've slept together since (most recently like 2 months ago). And there's another friend I took comfort in this summer after my previous relationship ended, whom I have also slept with before and suspect I would again if I wasn't with someone I really cared about. Would much prefer to stay with the guy I'm with though.

Can you condense the text into three sentences or less?
<bot>: Would feel dishonest hanging out with previous fuck buddies/people I've dated/slept with without telling my bf. Don't know how to (or if I should) bring it up.
