2 sessions with Helix. First Post - mild sensations

Hey BlackDamp, welcome to the Forum.

I think 26 is a great age to start. Enough maturity to proceed cognitively yet not so mature as to be 'hard-wired' into a mindset where sensual arousal and orgasm are identified solely with reproductive sex. Relax, BREATHE, sense, enjoy and you'll move forward nicely. You should gain a new view toward sensuality and an in depth understanding of human orgasm from the perspective of both sexes.

Finding, "the spot."
It's not going to feel the same time each time you insert and have a session. Sensation will change as you awaken a stim spot and will change depending on your degree of arousal. (Many times you'll get whipped up into an Overly aroused state and that will kill your session --- plan on this happening!)
For now, relax, breath, vary positions and action. Work downward to the point where the sensation is barely detectible.)
Aside from the 'plug-n-play' crowd that Super-O's within 5 minutes of their first insertion, most (probably >80%) of us spend up to a dozen sessions just getting our navigation bearings.
Helix is a nice tool that's pretty versatile (it behaves differently depending on body posture, lube, rectal cleanliness etc.) Contrast that with the MGX which, in my bod, tends to stay pretty much next to the prostate regardless of the above factors.) So, patience is a virture with Helix and it should give you a nice variation in vibes for a long time to cum.
Using Helix You'll probably get the most prostate contact when you're on your stomach.
Well lubed and relaxing on your back with a very relaxed rectum, Helix will settle on your posterior rectal wall and massage that area for some very nice anal vibes. ("relaxed" may not start to happen until somewhere after session 15). So be alert to which position gives you the sensation you wish to explore and make some notes, mental or otherwise. As the weeks or months go by, sensations will change as you awaken more nerve endings in each area. I was lucky and found my prostate during session #3 (with a Helix).
You'll hear a lot about pre-cum in the Forum and blogs. It's of no real concern but is an indicator of cowpers contact and for me tends to be more pronounced with MGX, somewhat less with Progasm, insignificant with Helix and very psychologically related. I 'drool' a lot when turned on and produce a lot of musky pheremones that my wife finds attractive.
Practicing relaxation and stress reduction will yield you the greatest benefits and return. That said, an outright raunchy session of anal action can be outright fun; butt, rest assured that it's not going to yield an orgasm. (This cums from one of the more anal guys in the Forum.)

Flaccid:
No sweat. This varies with guys and with the occasion. When you use an Aneros during foreplay you'll probably find that you can erect, "on request." We made major changes in how we approach foreplay, penetration and our approach(s) to climax.

Random twitchings:
Over the long haul, these seem to reduce in number, frequency and intensity as the brain begins to channel it's orgasmic energy in a more organized fashion. Should you like a particular twitch; cherish it, mentally focus upon it and someday you may experience it again. However, if an orgasm of the left pinky isn't your thing, ignore it and your little finger or toe may never twitch again. Don't feel though that you can CONTROL things. At this point, just be alert and enjoy the ride, wherever it takes you.

Identifying the higher-order sensations:
If you've been into tantric sex, severe denial or heavy edging as you approach ejaculation, you've got a fair sense of the difference between your orgasm (wet-O) and the ejaculation itself. I was weak on this and it took me a while to get a handle on these as individual entities.
Orgasm is what happens in the 4 inches between your ears. Your brain may hold it right there and 'go spiritual.' It may add in an auditory or visual area of the brain. It can turn on a part of your bod to join in with the mental party, sometimes pointing or reflecting the energy back to where the stimulation started. This may be a wet HFO with either a pulsing ejaculation or a streaming flow of semen (some of us trigger these with our nipples). The wet HFO is about as close to something 'sexual' as we cum, Anal Orgasm (cyclic anal and rectal spasms at about the same frequency as ejaculation), Whole-body reaction (toes to eyebrows, more like a heroin junkie might describe). Some are extremely muscular, most involve some cardio excursions and will leave you sweaty and stinking nicely to the opposite sex (maybe limited only to your mate) and perhaps to one of your gay brethren should he be standing downwind from you. Depending on the degree of fight-flight response in your brain you may have some panic as you enter orgasm. There's more in the Wiki. Fear not, no one in this Forum has reported their own death from panic -- and the reported body count of dead guys with plastic up their ass remains zero.
Good news is that your regular reproductive orgasms will always be an option when you wish to 'breed.' You'll be better able to distinguish ejaculation from orgasm and the length of that orgasm will probably increase.

There you got it. Hope this answers most of your questions. We're here to contribute and help.

Enjoy.
