I mostly only know hetero people, there are a lot of them out there!! Mostly they’re pretty cool.
I guess chose the one you trust the most (and crucially who is safe to come out to) and try it with them first? It’ll give you a sense of how being out to even just one person makes you feel and what saying it was like. And don’t beat yourself up if you blush or cry or say something really crazy. I was terrified when I came out, and stayed terrified and sort of ashamed (internalised homophobia) every time I did it for a long while.
And take your time, you don’t have to tell anyone until you are ready. There is no rush
You will get a lot of practice at it eventually because unless you look really gay you’ll be coming out to people forever, to work colleagues, neighbours, new mates, delivery people, random women on the bus. Although you can chose just not to bother sometimes, I’ve just nodded along a few times when someone who I’m never going to meet again has asked me if my kids get their eyes from their daddy.
Good luck, no matter what happens, it’ll be okay in the end
