u/this_is_no_where

I’m currently out to my wife as bi and we have had an open relationship for 5 years and a sexless marriage for almost as long. She knows I’m mostly attracted to men, but doesn’t know I’m exclusively attracted to men (something I discovered only after having my first MM experience 5 years ago, which I’ve long since confirmed). My question is, especially for those who have been in similar shoes, how do I best come out as gay?
