至 NakedKiwi :You're right, it's your cock and your decision what to do with it. If at some point you can't get it up anymore. I use my 4-channel TENS on the back to achieve a deep effect and never on genitals.
至 baldlips :I realize that, but you do understand that the output of a TENS is really no different to that of a dedicated e-stim unit? Just different waveforms. Also you said you have a 4 channel TENS unit that I presume you use?
