Need some help (normal hands-free orgasm)

My take is, if what you ejaculated was very liquid (not thick like cum), it was your prostate being milked. Everyone is different as far as volume of pre-cum ejected from the body. If you felt drained, you had penile ejaculation. If not, then it would be prostate fluids. I would not worry about it, have more sessions without touching your penis or having it touch anything to encourage rubbing. Good luck..

When I first stared out, this would frequently happen to me if I was on my stomach. The pressure of my penis pushed into the bed is enough to trigger ejaculation in most cases. Also, if you're in a position that stretches the skin tightly on your penis, that can sometimes be enough stimulation to trigger ejaculation.

I have had the same expierence as the topic starter. I have had the aneros for over a year and nearly every session ends in a hands-free traditional orgasm. Note that I do not touch my penis at all nor do i use a position where my foreskin is tightened. One way or another prostate stimulation still leads to ejaculation in our cases.
Recently I thought about this and came up with the idea that the aneros massagers may stimulate my prostate to aggressively (or my prostate is too sensitive?). I then decided to try something new and buy the peridise duo set. It led to an interesting new expierence:
After insertion and contracting for a while, my arousal levels increased quickly, with the feeling of imminent ejaculation approaching (just like when using my helix syn and progasm Jr). I tried to edge on this level for a while. After a few minutes, however, I felt like I passed the point of no return and expected a full wet orgasm. This didn't happen: instead my penis throbbed once or twice and I ejaculated a single spurt of cum. By the smell and taste I knew for sure that this was proper cum and not just precum. I didn't have the feeling I just had an orgasm at this point and tested this by starting to masturbate. After only a few moments I had a full ejaculatory orgasm. I'm going to try to repeat this experience sometime soon.
Bottem line: you might try to use a different model as your body may react differently on it than the aneros prostate massager you're using now. To me, the peridise seems to deliver more subtle stimulation to my prostate. It still leads to fluid expulsion, but not to a complete ejaculation.

@cko23 I have the Peridise set as well. I notice particularly when I am greatly aroused and the Peridise is fully inserted, I feel like (with time) I can reach the PONR. Not sure if I could ejaculate this way but a great feeling!

You probably can :). Have you ever had a hands-free wet orgasm with another aneros model (or any other toy)?

Never in my life had a hands-free wet orgasm. I'd love to experience that!

It needs a little practice but I think that everyone can learn to achieve this; the description in aneros wiki on the super t shows similarities with the technique I use ,although the wiki- technique involves touching the penis, which I don't. If you'd start with the wiki-technique and gradually reduce the amount of direct contact with your penis, you'll eventually be able to have a hands-free wet orgasm.
