I think most important thing is to place your electrodes right, so you won't be distracted later on with adjustments. When I'm distracted, the pleasure starts to go in a wrong direction, you can loose erection and then you get stinging feeling instead. This distracts even more, so the circle closes. To avoid that I follow several rules:
- when using sticky pads I'm using clean & "fresh" ones, also I put them after shaving & cleaning. Also I'm avoiding places where the sticky pads can fold. If i'm using sticky pad for cock I also place a simple rubber band that prevents from slipping
- when using circle loops or homemade corona cap I'm using some conductive gel. This is the tricky one because gel is slippery so it's not easy to keep electrode in place; a simple rubber band helps, as well as the condom (It's actually even better with condom because you don't need to refill the conductive gel)
- keep in mind that fellings are very intense so you had better clip your cables tight. I often tremble and move, which makes a risk of disconnecting
- If you want to watch some porn, just prepare it beforehand. Jumping between movies also causes distraction. Just choose one longer movie
- finally, the 2b settings. It's good to be aware of which knob does what as well as knowing the programs. I even found out that If I'm focusing too much on the knobs I get distracted again. This is why audio cd or other mp3's are good. Just push play and forget. There is also a surprice effect when you try the track for the first time. Anyway, If you want to stick with original programs, my favourite are:
-waterfall 80/65 going down to 15-20/65,
-waterfall but in opposite direction - from 15-20 to 98 (this also requires turning the power up a little bit when increasing adjust),
-throb 65, thurst 50- these two works for me best at the end of session. 100 is also a fine value here
-pulse/bounce around 15-20/50 , just set the adjust knob to stretch the "pulse" signal; somehow I don't like ultra short pulses
-A/b split - continous feeling on cock and pulsating one for ass
I haven't find a good setting for milk, microphone, step, random, training... yet
And finally, just be super-horny when doing it.
