Ah I had never heard "heterosexism", I learned a new word. I just checked a bunch of definitions, and I would now use "heterocentrism" for presumption of heterosexuallity - it's possible to presume that without thinking it's the norm, but just because in practice in many places it's more common. Just like when I hear someone named Daniel(le) I assume it's a man because I know more man Daniel than woman, but I do not think there is anything wrong or abnormal with a woman named that way. So yes I would kind of reserve sexism (or heterosexism now) for cases when the remark carries some negativity related to a given gender (or sexual orientation). And I still stick with my original impression that OP did not carry any negativity towards women (at least we can fairly give them "reasonable doubt"), but that they were just making a joke about living with someone else in general. Sorry for the long thread and I hope I have not offended you. I'm always interested in having other points of views so I like this kind of discussion. Also English is not my native language, so there might have been things lost in translation.
