"could you hand me another beer, and oh yeah, I'm gay"
not being flip, that actually works quite well
I tried the long tortured life history self evaluation of every thought since consciousness approach a few times with degrees of the shock of self discovery and time testing to see if was all real etc etc etc etc
boring, lengthy, who cares, bored me and was much to much explanation
my best friend, my closest friends, basically took the fact statement "oh, by the way, I am gay" and asked what questions they had which were few and we went on to other subjects
I was a bit older though when we had those conversations, I can imagine if we had all been younger there might have some different thoughts on it but still for my best friends it was no big deal and no one ever had a bad reaction, I lost a few friends along the way but not anyone I cared about, and that was their problem
and honestly the only reaction from a friend that I can remember was a close friend who told me that I had to tell her husband in a few days since she didn't feel comfortable living with that secret without telling him since they had no secrets - I wrote him a short letter since I wouldn't be seeing him and that was the only time I wrote it out - he got the letter and never said a word, next time I saw him and forever after it was just as it always was
that I can't remember any other reactions tells me that it was no big deal for them, just for me to say it.
My father had the best reaction - he paused, and then said, "you aren't the only one in the family." I asked him who, he said it was not my business, and that was that. (I am suspicious of an aunt... but then, I always was with her)
any for my friends - they hated my now ex-partner (they had their reasons), told me I could do better (they were right that that had to end) and have always been cool with my talking about guys I meet and have hopes for - but that is just one of many things we talk about, when we talk sports, movies, family, politics, life, whatever we always talk (and talked) about
relax - it is a bigger deal to you than to the people who love you
