French for pony, dates back to the 18th century. Today, the bidet is installed near the toilet, so you can be refreshed after using the toilet. Male or female, you straddle it, either facing the faucet handles or away from the wall. You can fill the bowl or wash in the spray. There's the traditional "rim-and-spray," w/ upward spurt in the middle. Or, the simpler "over-the-rim."
