They smell you on things you touch, like a tv remote.

It reminds them of your hands, which probably makes them feel good because your hands pet them.

The rubbing against the face is enjoyable for the reason you already mentioned - they have glands on their faces that help them rub their scent on things, so it feels good to them when their faces are rubbed against. It’s an instinctive reaction.

I think the differences between a wealthier, urban individual from different parts of North America (ie LA/SF vs NYC or Chicago) are smaller than the differences between someone who lives a rural life in California or Oregon vs someone who lives in upstate New York or rural Pennsylvania.

While there are definitely cultural differences related to the history of an area and the peoples who occupied it, money and privilege that come with an urban life tend to blur those lines a bit more.
