I rarely ever walk up to someone and say, "Hi I'm Dag and I'm queer." But I also do not censor myself. If I'm in a car with someone and I see someone attractive I will say, "Ooooo, he's cute." If a co-worker asks which actress I think is hot, I will tell them Russell Tovey.
Most new people assume I'm straight. But I've almost never told anyone I was queer. Almost no-one has ever asked ME if I was queer. But everyone ends up knowing in the end.
But when someone is being homophobic, I have looked people in the eye and told them that I like getting fucked in the ass.
