@Vanessa1511 I don't think there are any different rules for different countries as far as stating the gender you accept. And it doesn't matter whether you share your bathroom, kitchen, hallway, whatever, with guests, as a host who shares living space with guests, you can state that you only host females.
I don't think Brian was putting forth the notion that Egypt is liberal- he said "for the area". In other words, it's more liberal than countries where women have to be covered from head to toe in public, including their entire face, only having a little screened slit to see out of.
