“The next day was the ‘hands on’ part of the workshop. Betty explained the two main types of orgasms, ‘Tension-Release’ and the ‘Rock 'N’ Roll.’ Tension-Release is when you squeeze your whole body and PC muscles ("pubococcygeus muscles," the thing you squeeze when you're doing Kegels) and kind of force an orgasm. Rock N’ Roll is where you squeeze and release, squeeze and release, and then slowly over a long period of time build to climax.”
