I recently had a session with my Progasm Ice early in the morning. The session was good and lasted for about 30 minutes. Moderate P-Waves and good prostate isolation has been the norm with the ice. It doesn’t seem to move as easily as the Helix Syn. So around lunchtime I was feeling some a-less sensations so I decided to make time for another session. This time I used my Helix Syn. I started into moderate P-Waves within the first 3-5 minutes and a full blown orgasm; body shaking, involuntary contractions and moaning, writhing around, within 10 minutes. Holy shit what a session! I highly recommend this method for those who have both the Ice and the Syn.
