Needless to say, it didn't turn out to be the orgasm aid that we'd hoped for. She said it tickled and turning up the intensity didn't help it feel better.
Using estim to produce an orgasmic or pleasurable response is first of all dependent on the brain, that giant sex organ between the ears, fulfilling those expectations. Sometimes there is too much expectation, it doesn't happen and there is disappointment. This is also the case in other forms of stimulation too and only experimentation is likely to inform on what pleases and what doesn't.
Then, in estim, there are countless variables and all have a part to play. Amongst them there are the type of electrodes, the position of them (and a millimetre or two can be critical), and the electrical stimulations applied. Even conductivity at the point electrodes are attached is a factor. There are NO SETTINGS that particularly suit all circumstances/ positions and electrodes. It's an inexact science!
I recommend that you set aside playtime for experimentation with no particular expectations - and make it 'play'time too!
You mention stimulation of breasts and nipples. Be aware that the placing of electrodes which 'cross the heart' can be dangerous, even when certain Rules are followed, with specifically suitable equipment.
See http://www.e-stim.tips/for-beginners for some information - pay particular attention to 'Across the heart', 'Nipples', 'Isolated channels' and the difference between Bi-polar and Mono-polar electrodes.
Play Safe - Stay safe!
