Everyone I know who is bi/ gay/lesbian and what other people to know about it just drop it into normal conversation at work. Like this
my parter and I went to Paris last year
what did she think of it ?
Actually my partner is a man, he’s called Steve, we’ve been together for 5 years
ok, cool so what where do you stay in Paris?
someone might say
sorry I just assumed it was a woman, hope I didn’t offend you
and the correct response is “ no worries”.
No one is asking you not to chat about your life or answer honestly, just like everyone else. The number of people at work who actually care about the sex of your current or former partners is vanishingly small.
they mostly want to talk about Paris, or footfall or what’s on the TV.
what WILL seem totally weird is if you have been working somewhere for years and everyone talks about their partner / kids / dogs and you say nothing, because you are convinced that they are all hateful bigots who won’t accept you are gay / whatever .
so people will naturally assume that you have no partner / kids / dog. Then you suddenly announce two years down the line at an Awareness Event that you have a partner who is the same sex and a cat and you were scared to tell anyone because of the heteronormative bi phobia / cat phobia exists in your workplace. And that you have been deeply hurt and traumatised every single day for the last two years because people have assumed that you were straight.
THAT is what will mark you out as weird and attention seeking.
Tell people or don’t tell them, it’s your choice. But don’t blame others for your choices.
