Welcome! There are many versions of coming out all over the site, but you might try a tag search
to help narrow it down a bit. If you start typing "coming out" into the box, the various tags like "coming out to family" and coming out as poly" will pop up and you can pick the one that seems most applicable.
Do you plan to come out to everyone (work, family, friends, etc) or just those you're closest to? I know many people have to keep their relationship status a bit hush hush because of careers and all that which can really complicate things when you're deciding who to tell and how to say it.
