Female, technically more pansexual but I happily take part in the bisexual community in the UK [1]
Fun fact: I personally found it helped me to be queer when you're a woman in IT. I've generally found creepy guy control much easier by being A. butch, and B. generally stating I'm not interested in guys [2]. I was able to handle awkward interview questions along the lines of "But you're a GIRL" [3] by claiming to be "one of the boys". This doesn't mean that all of this wasn't a painful compromise, and I know I was ultimately confirming to heteronormativity rather than smashing it. But we do what we must, not because we can, but to survive.
I'm currently working on getting an LGBT+ organisation started in the office. If you have any experience of running one, or are generally LGBT+ in the UK, feel free to get in touch :)
