Very recently, I finally was able to sound a woman. I met her online 2 years ago, and she finally passed thru NYC on her way to vacation with her family.
I wanted to do this with her because she is very experienced at sounding herself, and so I would know if I did something wrong -- she'd tell me.
She actually uses minimal sterile techniques -- partly based on what an EMT told her, and partly on her own extensive experience. She said that taking a lot of cranberry is her main secret.
She wanted me to use a metal sound (she uses a nylon rat tail comb handle at home), so I could attach my ET-312 estim device to the sound and her clit. I cleaned, alcoholed, and soaked a sound in boiling water. I used betadine around & inside the opening of the meatus, and lubed the sound with Surgilube repeatedly. I wore latex gloves. She, however, kept sticking her fingers there.
We did that, and she says she was in an almost continuous state of orgasm for 2 hours. Just what she waited for & wanted for 2 years. She had some incredibly strong orgasms during this time -- some just from my moving the sound itself, without any electro. And she liked having the Hitachi Magic Wand on her clit at the same time. (Next time I'll try the metal vibrating sound as an estim trode, to combine all these in one place.)
She said it was wonderful, and after taking a lot of cranberry, had no problems.
