It’s your spouse. Don’t tell them anything that will lower their self-esteem. Don’t tell them about things you know they will be jealous of. Don’t brag about what you think are your accomplishments in the bedroom, rest assured, her skeletons are far worse than you can handle knowing about. Don’t talk about the past, you can’t do anything to change it, neither can she.
Focus on being happy now and enjoying each other right now. She married you because you made her happy and feel safe, kept her laughing, made her feel great… do the things that make her feel this way.
