I do.

It's common enough that it has an acronym (LAT), and name "Living apart together":

It's not super-common, anywhere, to the best of my knowledge. But it's also more common than you'd expect.

I enjoy LAT. Keeps the fire alive in the relationship with the LTR gf. And gives me enough space and freedom, to not feel trapped.
