Is it trusting to share how many previous partners you have had and vice versa with your partner?

Do you think this would build trust and understanding? I think it would be healthy to be open and discuss it, there’s no shame in it and I don’t think it would harmful. It’s good to know about the promiscuous times and we’re all adults it’s part of life and we have a history one way or another, I don’t think there’s harm in being open if they were to have slept with somebody you know and they be forthcoming rather than it be a secret? This was all done outside the conformities of the relationship.

Would it be healthy or do you think as a whole it could potentially bring jealousy or friction?
