Shower head orgasm

So when I feel that pulse in my vagina do I keep the water going on me or stop? When I feel the pulse I starting humping up and down let out about 2 feel good cries then stop but I’m not sure I’m reaching full orgasm here.. help?

Also I find it way longer to reach orgasm just laying on my back. I use my left hand behind me to hold myself and the other to push the water on my clit.
