I just got violated by my toilet

I got here yesterday and have been adjusting pretty well so far. I've gotten familiar with my area of Tokyo, met fellow teachers and have gotten used to the stares.

In fact, I was feeling pretty good until I let my curiosity get the best of me in the bathroom. There I was, sitting on my throne when I noticed a "shower" button on it. It didn't occur to my inner George to press it after I completed handling my business.

Word to the wise, "shower" does NOT refer to the cleaning apparatus sitting .005 feet away from from the toilet. It refers to a toilet spray that provides additional cleaning to all parts of your nether regions. In reality, it's not a bad idea...for women (whom I believe they're meant for). But if you're a guy. And you're not expecting it. And the stream is relatively hot...

Eh.

I was ready to kill someone. NOT the kinda culture shock I was expecting. In my country, toilets don't give enemas.

Update: 2:40am
It was recently brought to my attention that these are called bidets and are apparently all the rage in France
