I got the Aneros Helix Syn V a couple of months ago and have been occasionally playing around with it working towards a prostate orgasm. I’ve had mild success before; a little bit of shaking during long sessions, but nothing to crazy and definitely no hands free o / super o.
I saw a post here saying that before your session it helps to edge for a little bit so I did just that. I jerked off for maybe 30 min and brought myself close 10 or so times.
I did this late at night and was in a very relaxed state, which probably helped a lot. After a bit of fun (no cumming, though) I decided it was time to start with playing with the toy. I took 10 or so min before starting to hit my weed pen and to make sure it had been a bit since I touched my cock.
Laying down on my bed, I lubed up the toy and after rubbing it against my hole for a bit I gently pushed it in. I started the session with the vibration off and just trie to focus on contracting. I also made sure that I tried different types of contractions; I saw a post saying that they didn’t have to be big ones and found that I had the best results with little contractions.
