My husband and I engage in threesomes often, sometimes with a woman and sometimes with a man. We've been seeing the same woman for about 4 years and never had any issues - I think because we are all being honest with ourselves about the situation. We love her and she loves us, but it doesn't change anything because we all know who we are and want we want out of this.

I appreciate you talking about the upsides of this dynamic, because there can be many, but there can be downsides too if not everyone is being honest or responsible.
