What is this thing doing to me?!?!

I think you are learning about prostate "rewiring". There is more to the male anatomy than 'bating' to orgasm. The prostate orgasm (via Aneros) adds IMHO another dimension to the male orgasm. Have you tried binaural beats? Erotic hypnosis? Erotic fantasy? All of these add dimension to the male sexual repertoire. The fact that you are abstaining from ejaculation is, IMHO, a step in the right direction and is adding yet another dimension. Exploring your male sexuality is what it is all about!

What on earth is this thing doing to me?!?!

The Aneros is doing nothing TO you, YOU are doing it to yourself ! You have voluntarily embarked upon a potentially life altering journey, by opening your mind to the possibilities of pleasures beyond anything you have experienced in the past. It is the courage of the adventurous soul to delve into the unknown that can change one's reality, this is what YOU have done FOR yourself. You have discovered, like so many other men here, the deeply satisfying pleasures to be had from prostate massage and the resultant desire to increase those pleasures by not repeatedly depleting your Chi through less satisfying ejaculatory orgasms. You've, perhaps unknowingly, begun following a Taoist/tantric path toward personal fulfillment.

As @goldenboy noted, prostate orgasms do add another dimension to your whole being, this dimension is not one which can be easily verbalized but can certainly be perceived on both conscious and sub-conscious levels. Many men have noted their decreased pursuit of ejaculatory orgasms as they discover the energy buildup (arousal) which can occur from temporal abstinence. Aneros practice relies upon high arousal levels to produce high pleasure responses, you've discovered for yourself one of the arousal amplification paths which can make the magic happen. This has been discussed in numerous threads on the forum, here's one you may wish to read -> Aneros, Arousal & Abstinence. Good Vibes to You !

Yes :), I have tried both hypnosis and binaural beats, I seem to get more out of the latter. What an amazing journey.... I have a session once per week, and it seems like they get better each and every week. Simply amazing.
