Thanks for sharing this.
I doubt I do really understand it. (Plus, I'm not knowledgeable with regard to the various sexual orientation labels that are in use nowadays.) I thought you did an excellent job of describing a complicated situation though. And, as a result, I think I at least got the jist of what you are dealing with. One thing I do think I can relate to is what you wrote about the subject being "painful to talk about - and embarrassing."
I have a whole lot of that I carry around with me 24/7/365.
Best wishes...
