I found this helpful. But it also seems worth pointing out gender differences here.

What I’ve learned from living with male housemates: I operate from an US mentality, as in, what do I need to do to benefit the community?

They operate from a ME mentality, as in, what will get me what I want?

Men won’t respect women’s boundaries on the regular until there are legit social and professional consequences for disrespecting us. Right now, there’s just not.

The problem is not entirely that individual people don’t practice good boundary hygiene. The other problem is that plenty of people don’t give a crap about our boundaries.
