Thought I’d write down how this process went for me (M39). Maybe it’ll help someone else along. I certainly have benefitted of being able to look up other’s experiences on here.
Got an Aneros (Helix Syn V) roughly 5 months ago, quite randomly read about it on reddit. After the first few sessions found that the ‘stairs climbing/ hip rocking’ method allowed me to start feeling where my prostate was. Usually spent 1-1,5 hours on a session, once or twice a week. The initial 3ish months were interesting, but in general I approached it quite actively. Which led to nice feelings, but not the orgasm build up feeling. The first major roadblock I hit about 1,5 months ago, muscles contracting too hard and ejecting the toy on the run up. I got around this by using a towel wrapped around the butt and holding opposite ends, to prevent the toy from getting ejected. This led to the first session of multiple wet orgasms/squirting? kinda thing. This was a bit of a breakthrough, although it felt I squeezed/forced it out. Too much pressure on the prostate/cowper’s gland. At the end of the session I relaxed and stopped moving and that was the first time I started to feel the hint of an ‘orgasm feeling’, that was totally separate from any anal nerve area sensations.
