This is just one of the many things straight people take for granted, the assumed openness in conversations people have when they have no fear of being judged or viewed differently for an "alternative lifestyle." I work in New York where it should be more than okay to be gay. The truth is I probably will not suffer any consequences if I openly discussed my orientation. But from years of gauging environments I have found that even in the US, my personal life is still referred to as "cute," met with a blank stare and a topic change, or worse, faced with ignorantly offensive questions. I still get asked who the man or woman is in my relationship, and I still get told that my sex life is hot. A man I didn't know once approached me with sex tips he thought I should perform on my wife (with my wife beside me), as if I needed his help. I also get asked what I would do to have a child (as if it's impossible, and as if it's every woman's objective). As a result, I hardly volunteer my personal details to people I don't care much for. Sometimes it's better to be glossed over than to deal with this kind of intrusion.
