getting started

I recently purchased the volcano pack and used both models for about a dozen sessions. I have yet to experience a super o or a hands-free ejaculation.

I've followed the online instructions and other suggestions in the Forum and Bee-Line with very limited success. I have yet to experience the involuntary contractions. Maybe I'm not holding the half contractions long enough. I know I am massaging my prostate because I do have pre-cum. At times, I feel tingling in my penis and the sensation that I am about to ejaculate, but no ejaculation. Is that common? Is that what I'm supposed to feel? Like being on the edge?

One positive note - when I finally ejaculate the old fashion way, the volume is much more and it feels awesome.

I would appreciate some help in getting to that next stage.
