If the bidet has both hot and cold water controls, start by turning on the hot water.  Once it's hot, add the cold water until you have a comfortable temperature. Be very careful when turning on the water, as many bidets can produce a very high jet of water with only a slight turn of the control. You may find that you need to hold the control to keep the jets on.  In normally hot climates, such as the Middle East, you should start with the cold water. The water will not need time to heat up, and you may end up burning sensitive areas if you turn the hot water on first. Be sure that you know where the water nozzle is, or you could end up with a surprise shower. If your bidet does have a spray nozzle set in the bowl (unlikely in the UK due to regulations), place your hand above it to subdue any jet of water and then either press or pull the diverter lever between or immediately behind the taps. Sit or squat over the stream so that the water hits the area you need to clean. You can continue to hover above the bidet, or you can sit down on it. Note that most bidets don't have seats, but are still meant to be sat upon; you just sit directly on the rim. Some bidets do not have jets: they simply have a faucet that fills the basin, much as you would fill a sink basin. In this latter case, you'll need to use your hands to manually clean yourself. When you use a mechanically handled bidet after you had finished the "job", you don't do more than use the external mechanism to turn the water jet nozzle to the center of the bowl and turn on the water supply valve, which is on your hands reach beside the bowl. On those bidet types, as the water jet is very thin, you don't usually feel the water temperature. Of course, in some cases you can use warm water, taking the water from the bath's supply. If you're using a bidet with a jet, then you can mostly let the force of the water do its work. If you're using a basin, then you'll need to get your hands dirty. Either way, you might consider using your wet hands to "scrub" the area clean more quickly. You can always wash your hands afterwards! Consider combining the bidet with toilet paper. You can use the paper at the end, to finish the job, or you can dampen the toilet paper in the water and use it to wipe yourself clean.
