Social norm that seems to have changed when I wasn’t paying attention: having roommates of the same gender.

I think that when I was growing up this was considered normal? Idk? And now my female friends seem just as likely to live (platonically) with men as with women, as many men have suggested roommate arrangements with me as women, and I was briefly excited when someone said she would put me in touch with potential roommates recently before seeing that all of them were men.

Idk, does saying “female roommates preferred” just make me sound like a homeschooled Christian girl at this point?
