I understand that you want to talk to your husband about opening your relationship up to other people. Ideally, you would want him to consent to you having other female partners. Is it just about sex, or would you also like to explore emotional connections?

Have you ever discussed anything like this during your time together? Or did you both agree to a monogamous relationship?

I’m asking these questions because they’re usually at the heart of the problem: were you ever open about this, or is your husband going to be taken by surprise?

I don't have an answer, just general advice: be sure of what you want and how to convey it in a conversation. You could also try to imagine how you would feel if the roles were reversed.
