Well I think I can say I am on my way. Purchased the aneros (maximus) in February 07. The first few sessions were successful. Good feelings, some precum and more volume when jacking off. Then came a long dry spell with mostly dud sessions. In the last month things began to slowly improve with a better effort at lubrication and breathing technique.
I am married and have to be circumspect with the aneros. I showed the site to my wife but she is not interested. She has been away lately so I had more time to use the aneros in a relaxed situation.
The last four sessions have been wonderful. On 5/14 in a 1 hr 45 min session I experienced 6 2-3 minute mini O's of whole body shaking and the feeling I was on the verge of coming. Positon was on my back with a bit of cloth between the tab and me. Most of the action came within the first 45 minutes.
This was in the morning.
That afternoon I tried again with the maximus. I used plenty of lube and within 5 minutes of the start the whole body shaking O's began. plenty of moaning and groaning. Then the maximus began moving on its own for the first time. This produced about an hour of intense feelings with contractions. Best experience yet. Some precum maybe 3-4 drops. Abdominal breathing seemed to really help get the contractions going.
