I can easily have p-waves without an aneros

Hello,

For about 3 weeks i can easily induce the famous p-waves without a aneros (to be honest: ive just ordered my first one (Progasm Black Ice) a few days ago (but ive had a "Nexus Excel" which was awesome too). At first i lay down and arouse myself without touching myself. Then i start to slightly and irregular squeeze my pc muscle. I cant really describe how i squeeze my pc muscle but its a irregular change of squeezing and relaxing. I dont really concentrate on my breathing. Then after some time my pc muscle starts to vibrate (its like a flutter, are these the famous "involuntaries"?). When i conectrate on this vibrations i will get a pleasure wave. It goes through my whole body and is much more pleasurable than a normal penis orgasm.

Does anyone have experience with the same "technique"?

PS: Ive got the same feelings with my "Nexus Excel". The "Sphincter contract" method didnt worked so well for me so ive tried the "Do nothing" method, and it was the best method ive ever tried (8 pleasure waves in an hour). I´m a little confused because its under "Advanced Skills" in the aneros wiki. But why? It was a very easy and awesome method, and i was still a beginner. The Nexus Excel just moved on its own and i just had to enjoy. Is it even a well known and a much applied method?
