I’m not straight. Not straight. Did I say it loud enough? I'm. Not. Straight.It took me until I turned 21 to admit this and come out as a queer woman. Now, I feel ashamed that I was closeted for so many years; using ‘gay’ as a derogatory term like the other kids at school, waking up in cold, humiliated sweats after dreaming of girls, and lying to my parents about my sexuality.It’s taken a long time for me to feel able to admit that I am attracted to both men and women, so now I can, it’s frustrating to me that people constantly assume I’m straight.It’s unlikely that I would’ve so aggressively pursued straightness in my teens as the only ‘acceptable’ identity if I hadn’t grown up in an environment where gay was not ok. My parents are hardcore Christians, and both of them held intolerant attitudes to homosexuality. Then, of course, there was school. After I made the mistake of kissing a girl in Year 7, years of kids shouting ‘dyke’ and ‘lezzer’ at me ensued, until I eventually backed into the closet. Here, I quickly learned to see pretend-straightness as a safety net.It was only later, after three years spent earning my Bachelor’s degree at university, struggling with mental illness, and being forced to take stock of who I was and what I wanted in life, that I decided hiding my sexuality was now causing me more unhappiness than comfort. I was also lucky enough to be in a more tolerant environment in which to come out as queer. When I did so, it opened up a new world of possibilities; a world where I could go gay clubbing as a queer woman, become more politically engaged in LGBT activism, and have a long term relationship with a woman.Back then, a couple of years ago, when my ex-girlfriend and I presented as a couple in bars and clubs, we were regularly propositioned and harassed, and even filmed via mobile phone without our consent, and I felt unsafe going out to certain places. When I was on my own, however, people would assume that I'm straight, and still do – because the way I choose to present myself doesn’t immediately mark me out as queer.This concept is often referred to as ‘passing privilege’, and describes when a person is able to physically fit into an identity category to which they don't necessarily belong – in my case, as a straight woman. Although passing can sometimes make me feel excluded from the LGBT community and as though my queer identity is illegitimate, it mostly means that I can move through the world free from homophobic harassment. And for that, I am lucky.Those who don’t ‘pass’ as straight are often forced to deal with homophobia in their day to day lives, characterised by threats and slurs, social exclusion, and physical violence . The term is also commonly used when a transgender person passes as cisgender (cisgender is when one's experiences of their own gender agree with the sex they were assigned at birth.) In a transphobic world, passing is something that is often necessary to trans people's safety
