@Questionable,
Is this the latest fashion in kinky sex, or some addition to "sex toys" - actually don't answer that, but before you proceed with any such "foreplay" make sure you read up on the differences between voltage, amperage, DC and AC, and resistance. Is the lady sane enough not to point the taser to your head - if not, read up on electric shocks as "cure" for psychiatric conditions; and in any event, make careful notes on that experiment and come back and report!
