Japanese Women and the Cleaning of Ears

So Kawaii!

Seriously, what is the deal with Japanese women and cleaning others people's ears?

I've never heard of an american girl cleaning their boyfriends ears. If you even suggested it to them, I bet you would get some strange looks.  Or be out a girlfriend.

My Japanese girlfriends have enjoyed having me lay down on their lap as they put a special ear cleaning stick in my ear.

We shall refer to it as The Probe.
