I have never watched Jojo...but I know for a fact that control over electricity would greatly enhance sex.
Sorry for the science lesson but the Human body operates through Neuro-electricity, a special form of electricity that allows your brain to send commands to the body, and the body to send information to the brain.
By manipulating that, you could theoretically make someone feel twice or even three times more pleasurable in sex.
Make there body feel false signals of pleasurable function (Breast Gropes, Ass Slaps, as long as you've felt it before you could do it.) In Theory you could ACTUALLY mind break someone through enhancing the pleasure.
