Thanks for the reply =) I'm a scientist too so much of what you said makes sense.

You say that you no longer need to use the Key Sound to trigger off orgasmic sensations: how does that help with ejaculation control? Does triggering off orgasmic sensations release erotic energy thereby reducing the urge to ejaculate? If one wants to ejaculate, what does one do? Is it possible to control how the erotic energy is dissipated, i.e. through full body MOs or through ejaculation?
