A new woman started at work, a male colleague in our team seemed keen to get to know her. Then a few days later he said to 2 of us, 'Do you know that new girl is actually a lesbian?!'.
He seemed quite surprised. I asked him why he was surprised and he seemed sheepish and said he "wasn't expecting it" then made a joke about how you "can't tell these days". I wonder if he was assuming all gay women are 'masculine' with short hair and so on?
