Is is self harm or ok?!

Is is self harm or ok?

I have a friend who came to me with her deepest secret and she is looking for help and said that I could ask it here, just so everyone knows. It is kinda gross just to warn you.

She lays down in the bathtub and sticks her butt up into the running water. She says it is going into her Urethra. I am worried that it might be doing some serious damage.

She has been doing this once or twice a week for the past two years. Could this long term use also cause some injury?

Please give your sources so I can go there and print out what I find and show her that it is harming her or not harming her.

Thanks

She says there is a lot of pain that is almost unbarable when she does it. Why she still does it is beyond me, but she does.

The water is likely not entering her urethra. She might be having orgasms from the pressure of the water on her clitoris. Buy your friend a vibrator if you're that concerned about her health.
