On October 11, a book will be released titled Fashionably Late: Gay, Bi & Trans Men Who Came Out Later in Life [https://fashionablylatebook.com]. I have a short essay in that book about my own coming out. Fact is, many of us, though we may have known our own sexual orientation or gender identity as youth wait until late in life to "come out."
Back in April of this year, former Pennsylvania senator Harris Wofford recounted his "falling in love a second time, but with a man" in an opinion piece in the NY Times. I commend it to you for your reading — oh, and I hope you buy the book!
You can find Wofford's essay here: http://www.nytimes.com/2016/04/24/opinion/sunday/findinglove-again-this-time-with-a-man.html?_r=1
