Too aroused. Urge to just going for it is too big

@EpicReloaded When I first started my Aneros journey several years ago, I became so aroused following my sessions with the Helix Classic that I "had" to ejaculate. So I don't think your experience is unusual. Eventually, things settled-down for me and I suspect they will for you too! Just keep enjoying your sessions and let things progress as they may. There are no rigid "rules" IMHO! Just enjoy!

I wanted the strong orgams which occour through pure prostate massaging. The urge to just go for it is too big. What should i do? Did any of you guys also had this problem? How do i avoid it?

I think most veteran Aneros users fully understand the feeling/urge to go for those Super-T's but have come to understand the Aneros journey toward Super-O's is mostly a mental exercise where self discipline, mental resolve and focused intent account for much of one's success rate.

Avoiding Super-T's, at least in the early phase of your learning journey, is probably a good idea to facilitate positive rewiring. I'd recommend you read @Cockadoodle ’s thread Penis, NOT and @rook 's thread Whole Body/Whole Mind - the mental side & @SteelColdiron 's thread Aneros: The Essential Mind State for a little insight. It might also help you to read @neros 's post The truth behind how to "rewire".

I agree with @goldenboy 's assertion there are no rigid rules here, you get to make up your own rules, but there does seem to be a consensus on certain aspects of this practice which facilitate progress (please see Identifying Facilitators to Progress). Also as @goldenboy alluded to, your seemingly uncontrollable urge to 'go for it' will pass as you exert more self discipline. What he didn't mention, but I will, is his use of self imposed chastity devices as a reinforcement against an accidental lapse in self discipline. You too could employ this strategy to help pass through your current predicament. You just might find this fetish fun as well.

While it is well acknowledged that a high arousal level is necessary to enter Super-O territory (please see Are you "aroused"?), what is not often mentioned is that it is also possible to be too highly aroused. In that situation your body may be so keyed-up and excited that you may actually be seeking the relief, tranquility and sedation that a typical ejaculatory orgasm affords. This may short out the subtler pathways which can lead to dry-O's and Super-O's. Like most things in life, finding the balance point for optimal functioning is the key for continuing success.
Good Vibes to You !

Still on my journey but, for what it’s worth, I was exactly the same at the beginning. Where things started to change was when I began noticing sensations outside of my Aneros sessions. Gradually, the A-less has become just as pleasurable as sessions with the toy inserted.

Now that this has happened, I’ve naturally fallen into practising semen retention. I’d dabbled with this previously, but when I was enforcing it on myself, it didn’t work. It just created frustration. I guess because I wasn’t ready. What’s different now is that I’m doing it voluntarily and enjoying the growing arousal it creates. My frustration and urge to wank myself to ejaculation has gone because it feels like that’s spoiling a good thing for a few seconds of pleasure.

What might help - it did for me - was reading advice on multiple penile orgasms and practising techniques of deep breathing, relaxation and mentally moving sexual energy. I did this for a while and it changed my whole approach to penile wanking - and made it infinitely more pleasurable and long lasting. As a side effect, it sent my A-less progress racing.
