I never had the conversation before dating, but I’ve had it after I was in a committed relationship. It never struck me as an awkward or weird conversation either. It was always something that just came up out of curiosity. Hard for me to understand why everyone is shying away from the conversation. I’d have liked to see some couples who did know about each other’s pasts and just shrugged it off, because if you’re in a monogamous relationship, the past doesn’t matter.
