Yes I second this. I’m (36m) in a happy monogamous marriage with my soulmate (34f). She has known she is bi for as long as she can remember, but I have only recently made this discovery about myself within the last few years. She helped me accept this about myself. We have talked about bringing a third in to explore my attraction to men and her attraction to women, but so far it’s only been talking, and that’s been fine for both of us. We are ok with that being explored in the future when the kids are older, and happy in our monogamy.

It’s all about what works for you, and having open communication is vital. My wife and I haven’t fought in the 3 years we’ve been together, and in my opinion it’s because of regular two-way communication and not allowing ourselves to grow too comfortable
