Not all bidés come with a water jet that sprays your ass from underneath.
Here in Portugal it is a very common bathroom appliance. Only in our case, the model we use comes with a regular faucet (just like you wound find in a sink), with both hot and cold water
So, how to use it properly?
1 - Wipe your ass with toilet paper as you usually do
2 - Sit at the bidé, run the water and, using some soap, wash your ass as you would if you were taking a shower. Remember that this step is only to clean your butt off of any "residue" that you weren't able to clean with the toilet paper. So it's not like you'll be getting crap all over your hand (sorry for the graphic image). Besides, you're using soap and water, so it is all clean.
3 - When you're done, dry yourself off using a towel. We usually use towels that are smaller than hand towels. Anyway, once you use the towel to dry your butt,
don't use it for anything else other than drying off your ass (and don't share it with anyone else either) until you've washed the towel. This, I believe, is common sense
4 - You can pull your pants up without any risk of stains or wet spots, since you're all clean, washed, and dryed out
5 - Remember to always wash your hands after this (I'm sure you already do even if you don't use a bidé).
There you go, 5 simple steps. It's just a matter of habbit and I personally find it much more hygenic than not using it (it's a cultural thing, I guess), not to mention you can save some toilet paper too.
Other notes on the bidé:
- you can also use it to wash your feet if you come home after a day's work and don't feel like taking a shower.
- just as it is useful for washing twatts, it is also useful for a guy to wash his dick. Going down on a smelly pussy is one hell of a turn-off, so I think we should also do our best to make blowjobs enjoyable for those about to suck us
