I used to live over in Europe and there they have bidets [fixtures similar in design to toilets that are straddled for bathing the genitals and the posterior parts] and the one we had in our house had an adjustable head, and the water came out so hard like almost a pressure washer, no lie. I would wait until my mom was gone and aim that thing right at my clit and put the pressure on full blast. Damn did that thing feel good!
Now that I am back in the US and don't have one I tried so hard to find something to take its place. One thing that I found that works well is a house that has an attachable pressurizer (those things with the handles that you squeeze to control the water flow) that works really good if you just aim it at your clit. Another technique is the shower head. Mine isn't one of those hand held kinds, but I did notice that one stream of water seems to come out faster and harder then the rest. So I lay down in the shower and spread my legs apart really far, then I line up my clit with the stream of water thats the fastest and pump my body down back and forth while stimulating the area with my fingers. I try to hold it out really long before I climax by cover my clit with my finger and then letting the water hit it again. It works really well, and I love my shower time.
