Is it ever legit to talk with your date about past relationships of theirs/yours?

When I got back with my ex husband from twenty years back we talked about our ex's. Both general things and sexual. We found that being so open with one another has enriched our relationship.

Dont do it. Its a trap! Lol

It's probably a good idea to avoid subjects like failed relationships til the 3rd or 4th date (at least...especially if you're still bitter LOL) but otherwise, perfectly legit.

Sure, after a few dates.
