It seems like you are definitely ready, take the leap. You are correct in the fact that jealousy is the route to all problems, everyone has to lose that. I have been in polyamorous relationships and situations and use a threesome for the main characters in my novels, which many reviewers, from their writing, seem to find strange or as one put it “male fantasy land!” In my case, all the situations were started or suggested by the girlfriend at the time and it has happened to me on many occasions. I lived a peripatetic life while working on many overseas projects and I think it worked because those partners were also living that sort of life. It was because they were away from the influences of their own cultures, safe in the knowledge that family and friends back home would not find out.

In my novels almost all situations of the adventures of my “Dream Team” had actually happened, therefore I was somewhat miffed when book reviewers and other readers dismissed the situations. As my main characters are loyal to each other and are sharing lovers it would be ridiculous to take them out of the story on the whim of an editor/reviewer. It is the same for you in real life, go ahead and try and ignore the judgemental and critical. And most of all enjoy yourself, indulge each other.
