mini o questions

Hello all as a new user of the helix, not quite two weeks i have reached what i seem to think are miini os I will give a diary of my journey so far. the first week was mostly 90 minute sessions with one only being of pleasurable note this coming from quivering of the hips and upper body. after a 3day delay because of privacy issues i didn't have another session till this last Monday which because of taking some ibuprofen for lower back pain thesession was a bust nothing worked. On this past Tuesday I rinsed out lubed and inserted set down in the recliner with my laptop and read some of the forum about 30 minutes of this it was to the bed I layed down a towel and proceded with the breathing slow inhale while contracting lightly while on my back . I decided this wasn't going anywhere so shifted to my right side as suggested in the instructions finally after 2 hours going into the third i suddenly felt a slight muscle contraction in the small of my back which spred down to the anal spot and spread upwords through the testicles and upper body . it seems my whole body was one large contraction.The contraction lasted 3to 4 seconds and stopped . I took a 😕 breath and contracted the helix again lightly to hit the pleasure spot and again it started over this time lasting 2to3 seconds about the same intensity. I was able to have one more less time same intensity.The following night I followed the same procedure , this time the first one was longer 6to8 seconds the second wave was shorter only my back begin to arch and i started to become erect. Also with these i would have very fast rapid contractions in the anal area I am thinking these are mini os.
Am i thinking right on this? Will these become longer and more intense ? Whatdo i do to get them to continue on their own ? Will they be easier to obtain with more practice ? mY hope is to soak the bed with precum. Any comments will be welcome.
