I find this dilemma interesting and experienced it myself many years ago and even now.. maybe it is an age thing as younger people 'seem' more able.. however, I know that it is really still a problem in 'coming out' and I want to extend that to 'whatever disturbs us'.
People might have a problem coming out right now in saying "I love Russia" or "I believe in God" or "I don't drink alcohol".
To me, in a discussion, it is always contextual...
We all want to live who we are... and I get that but in reality and a discussion... is it wise to admit you are vegetarian when surrounded by meat eaters and you are living on an island? Over time everyone does adjust and in the end 'hopefully' a person in such a situation will be accepted.
I told my older brother when I was 43 that I was a homosexual. He gave the old 'we always knew you were that way' and I replied "but no one mentions the 'H' word... he went quiet and then I said 'homosexual'. He knows that I'd had a relationship with a woman.. so it might seem confusing to him... but in the end I opened up and everything was fine.....fine to the point that he actually text me once and said, "you would love this guys legs I'm working with at the moment (my brother was a plumber) and I think his number is on the toilet wall".
As I read your post I come to the point and this applies to me also, the real thing is "do you want to be out" and then - whether you tell him or others, is your business.
And if you do tell others, there will be a point, maybe, where you realise or think 'why am I introducing my self and at the same time saying 'and I am gay/bi/?' ??
Homophobic !! or Homohate?? that is another story that I'm yet to come to terms with.
I wonder if people who are Homo/? phobic are actually more scared of their own emotions/feelings/desires in that direction.
For what it is worth and I've posted this before... I came out to a school mate after 35 years and he said 'I know'... but he confirmed that he was straight but never pursued another woman after a bad experienced many years...
At the time I was scared of loosing his friendship, very scared... yet today as I type this I realise how crazy that idea was, because, I'd not seen him or tried to contact him for 30+ years... so the perception was mine to deal with ....
This is me looking back now but at the time, it was real fear...
So after all that... I'm not sure how helpful my post is but I'm leaving it as it is..
Good luck!!
