For hands free clitoral stimulation using a Clitrode
I have only ever used commercial e-stim electrodes when masturbating, but recently I joined a forum called SmartStim - http://www.smartstim.com and have learned so much about DIY electrodes from articles on there.
You can join SmartStim for free, but you need to be a member to read their articles. It's an excellent resource for anyone wanting to learn more about e-stim or electrosex, so I highly recommend joining.
It was while reading some articles on female e-stim masturbation that I saw some fantastic designs for clitoral electrodes or clitrodes posted by a member called "Tank Girl". Her electrodes got my attention as they look so functional and they intrigued me, so I started to design my own.
