A couple years ago, I tried several different models of Aneros. I got the most sensations out of the vibration models. I never did have a Super O or anything close to it. I finally gave up. My interest was once again aroused. I purchased a Helix Trident based on the beginners list and the sensations I was looking for. I started on my side, after a while tried other positions; on my back, on hands and knees, lying on stomach with legs spread. For an hour and half, I had precum with most contractions which were pleasurable, but nothing spectacular. I lubed up several times. I am preparing to have an hour and a half to two hour session again. I know the big O is there, I just need to be patient. Does anyone have any helpful suggestions?
