question about another kind of contraction

I believe you are on the right track. Part of this process will be some rewiring. Its apways best to be more subtle than rough with this.

@lighto i agree with darkbond, subtle is good. I believe what you are feeling is the quivering of your pelvic floor as you attempt to hold position, much like if you were to lean against a wall and squat, your legs would start to shake after a bit as they struggled to hold there.

What youre doing is great and as and as you become more aware of the tiny sensations in your groin, the sensations will grow in pleasure and intensity. Play around with the contractions: pull in more, pull in less, pull in as hard as you can at times, keep breathing the whole time. Make mental note of what feels good to you. I believe you’re close to bigger things, stay patient like you are and keep having fun, buddy!

@Some of my best sessions happen when I least expect them. I just 'relax' into the pleasures I am feeling. Like [USER="58120"]Neveryman[/USER], I don't follow a 'rigid' pattern of contractions. Sometimes, I assist and sometimes they are automatic. This mornings' session with the HIH 950 was supposed to be rather short; 30 minutes later, I realized that some of that time passed without my awareness! I had wave-after-wave of pleasure! I guess I just fell into a trance. IMHO, that is the essence of a great session!

... a month ago i discovered, that right at the start of a session when i'm doing a kegel motion reeeeaaally soft (like a quarter or less of a full contraction) my muscles start twitching. but not in a strong way like "the aneros device is fucking me" as other users described it, but more in a vibrating way.

First, I'd like to caution you about projecting other men's experiential descriptions onto your own experiences. Your body is unique in its subtle makeup, sure you're a human male and share many macro physical qualities, but you also have a unique biology right down to your individual DNA code. Your uniqueness should be acknowledged and celebrated, comparing your experience to others is a foolish exercise and just a waste of your mental energy. Even the basic concept of "fucking" can cover a very wide range of activity from the softest, slowest or still motion to vigorous, athletic almost violent dynamic motions. Where your body naturally ranges in this dynamic is going to be unique to you, so please. please, please accept and embrace what your body gives you, nurture those feelings you do have and don't worry or concern yourself with trying to match other men's experiential descriptions.

... in one session, i had a small rush (a kind of strong p-wave). but i'm not shure if this is the right direction as i don't feel any stronger p-waves (or have not learned to feel it yet).

It's wonderful you are tuning into your body as you are and don't worry about the intensity of the P-waves you are experiencing. As you become more experienced, the intensity limits of your P-waves will expand but even veteran users fully understand the intensity of P-waves will naturally vary within an Anerosession and from session to session. Your sensual journey using Aneros devices is an evolving process, it will change over time. As you rewire pathways in your brain, your mental perceptions of sensations will also change, sensations you initially feel during early stages of rewiring may fall away to be replaced by new sensations, this is just the natural path of the learning experience. IMHO you are proceeding fine on your journey, just continue to be patient with yourself.

... so my question is: are my spasms the right twitching for getting further on my aneros journey?

There are no 'right' or 'wrong' kinds of twitching/spasms, your body gives you what is natural for you, what is most important is that you are aware of and gratefully acknowledge the sensations your body does give you. It is your mental attitude which will most greatly affect your progress. A healthy, balanced mind/body relationship sets the stage for optimal learning on your journey. Your mind needs to fully embrace the sensations your body gives you and not try to impose it's ego in an effort to control the outcome of an Anerosession, let your body dictate the course of action. The basic rule of thumb in this is "follow the path of pleasure".

... or does it sound a bit to subtle for the involentary twitching everyone else is describing?

Initial sensations when learning prostate play are often subtle but as you become more experienced and attuned to your body the perceived subtlety decreases even though the actual measurable intensity (if it were possible to measure such sensations) remains the same, this is the nature of the mental rewiring which takes place during your journey. Again I caution about comparing yourself and your experience with other men, your body may simply not produce much in the way of involuntary spasms now but it may in the future, this is not anything you need to be concerned about.
Good Vibes to You !

Thank you very much for your feedback darkbond, goldenboy, Neveryman and rumel. It's really amazing how people in this forum encouraging new members with tips and feedback. I discoverd this also in other posts, but to experience it myself is really beautiful. Kudos!

So I had another session yesterday were I didn't focused on the spasms as a first step to something else. As I discovered also in earlier sessions, the sensations I get in the early minutes of a session are the strongest, and today I felt the P-Waves as clearly as never before. And as I can identify them now, I understood that I had them in almost every beginning of the session. I started relaxing my body and really softly touched my nipples, as I read in another post yesterday. The sensation arising from that was really crazy and after 10min, I had something like a small orgasm where the whole area of my prostata, penis and testicles got really hot and radiated through my body. After that, it was kind of hard to get the waves starting again no matter what I did, which was similar to earlier sessions.
But then the crazy thing happened at night when I went to sleep. I remembered the P-Waves and my really soft nipple play and got turned on by these thoughts. I started touching my nipples without the aneros inside me and had like 20min of fun with small P-Waves forming up inside me as long as I didn't let go of my nipples. Nothing like the small orgasm in the afternoon, but really enjoyable. So I think the rewiring process started and I'm happy I can name P-Waves now.

@lighto It sounds like your body is loving what you're doing. Nipple play is insane, isn't it? It's like there are jumper cables from the Battery (Prostate) to the power supply of the other car (Nipples) and when you 'turn the ignition keys' of your nipples, you blast electric orgasmic energy straight to your prostate. So cool that you are so new to this and your body is so in tune with the amazing pleasure. Keep it up man, and keep us informed of your progress!
