I am grateful that my wife and I love and trust one another like we do. We just kind of knew each other were bisexual from the start. You can get all sorts of advice here, and I feel just being genuine and loving is the best approach.
Being bisexual is just part of who we are. The boundaries come over time, and nothing comes between the love we share. I need my wife to have the freedom to experience the intimacy she desires with a woman and vice versa. We are better people and love each other deeper because of our transparency. Side note, neither of us are in a same sex intimate friendship today (though we want it).
I really hope you guys can be casual and understanding, because the growth in your relationship can be incredible. It’s not about the sex, it’s about being truthful & genuine to yourself and one another. Go for it and only think the best!
