I have experimented with masturbating in the bathtub for years, ever since my parents bought a 'shower massage' when I was in my early teens.
I learned to stand with it so the pulsing jet would hit my pubic mound which always made me come in a short time. Another method would be to put a facecloth over my clitoris and vagina and have the water pound me without it hitting me directly as I was too sensitive and found it painful.
I recently found myself single again and one of the first things I did after moving into my new condo was to install a massaging showerhead.
It worked; but was not the same as I remembered.
They say all great inventions are the result of accidents and I now know this is true.
I was at my local dollar store and bought this hose thing for watering plants. It has a large rubber cone that is designed to fit over the faucet with about two feet of thick hose on the end. The end then is attached to an on/off valve with a long thin hose to reach your plants.
The first time I used it, it broke. The rubber part came off the valve and I could not get it to stay back in place when the water pressure is on. I threw the long hose in the trash. Oh well it was only $4.
The next morning I went to take a shower and forgot that the rubber cone was still on the faucet. I stepped behind the shower curtain and turned on the hot water only to have the hose go wild and spray all over place. One of the places it hit was right between my legs. And it felt good.
That night I lay in the bathtub and tried different ways to have the hose shoot water onto my clit.
I found that it I turned the water pressure high, with the tub part way filled I could have the water jet spray directly onto my clit and the feeling was wonderful.
I have now made a holder for the hose out of a magnetic paperweight that has a plastic clip on the top.
I just place it on the bottom of the tub and turn on the water. I can sit upright, read, have a glass of wine and enjoy a relaxing orgasm while not lifting a finger.
