@PROcrastinator Mate, you are more than welcome. You are a writer, and so you should be able to write about anything, just try to do it well.
When I read books or watch movies, I don't think I've ever taken into account the sexuality or gender, or even the race, of the person writing it. I will know their name, when reading, and if I want to know more about them after then I will, but that's after. I think who you are doesn't make it strange. J.K Rowling's MC is male. George RR Martin has multiple female MCs. If gender doesn't matter, then why should anything else?
I've come out to most of the people I know within the last few days, so I just wanted to add something if you plan to write an LGBTQA+ Character, and if coming out is something that happens in the story.
It's scary. It's super scary. Not the fight or flight type of afraid but…
Imagine if you was in a family where everybody in it was a Baker. They only cooked cakes and buns, and sweet things, and you like cooking those sweet foods, but you also like cooking savoury foods, so you want to be a chef. You think, you could just be a baker, cause you'd be cooking sweet foods anyway, but you know you like cooking savoury foods and no matter what, you will always want to and without letting yourself cook those foods you're stopping yourself from being who you are, and from cooking savoury foods, and it might effect how you cook sweet foods because you'll never know what would make you happier. You want to tell your family because you don't want them to be upset or confused if you cook a pastry, and you don't want to waste any food because they don't want it in the house, but you do, so you're afraid you'd have to leave. You love your family, and you want to show them both your savoury and your sweet foods, but you're afraid that they won't love you as much, or they'll question every food you look at, thinking what if she wants to cook that. You're afraid of change, and you're afraid of not knowing what will happen. But you want to. That's what coming out is like in the worst analogy ever haha.
Once you do it, it feels great. Especially if they are accepting because you've let them see you and they love you anyway. It gets easier the more you do it too. I told a friend that I wasn't too close to, who didn't know anyone I do now. Then I told my mates. Then I told my Mum who told my Nan. All were great.
Finally, something that sucks. Being outed. This has been the most stressful three days I've had in a while. Monday I told two mates, both bi, that I'm Bi. Now when you tell people, you prepare yourself, put up walls, ready yourself. It takes a good half an hour. Or it takes seconds like ripping off a plaster. But either way, you do it. One of my mates told another without me knowing. She randomly said it while at a meal out with two other mates who didn't know, and the one mate who didn't tell. I wanted to leave, and cry and hide because I was so happy, then so scared in seconds. I don't know what would have happened if they weren't accepting, but it was terrifying. I wasn't angry. My mate was furious, but I wasn't. I was hurt, so sad, scared and numb for most of the day. Then I got home and burst out crying. My Mum came home, and I told her because I was scared of her finding out any other way.
This is an insight to coming out and being outed, I really hope it helps with writing, and don't worry, I'm so happy now, and everything will be alright.
