Re-wiring has progressed

Hi all i have not posted any thing since august, but i am still being re-wired i think, i have had success with the helix classic since having probs with the mgx but now i am having better luck with the mgx since i made a slight adjustment to it i placed a cable end protector on the hurting tab gives a bit wider girth to hit the spot better and is comfy no more problems there. It's basically a rubbery cap that stops damp going into the cables in storage, gives it a nice pad of just under 1/2 inch, comes off fairly easy for cleaning.
I use both now but am using mgx mainly because i have endless involuntaries seem to go on for about an hour or so plenty of pleasure waves, end less pre - cum i did not no the human body stored so much , plenty of involuntary shaking and moaning and all this has just started in the last week or so, and after a session of around 2 hours i'm knackered and knock knees turned to jelly. No mini o's or super o just serious pleasure. I can feel like i'm cumming though in a flash then you have missed it but it's just pre cum shooting on through i think, it feels nice though.
Another thing that has helped me i think is by keeping my briefs or boxers on nice stretchy nylon ones my favourites, with a piece of kitchen roll catching the runnning pre cum because if you drop the hold contraction a bit they keep the presure on the mgx against the prostate and keeps it fizzing as i put it, which is great then things go mad down there while wearing them i can let the hold off and away i go again with just the slight pressure,
Just one question if some one can answer it is it best to hold the pc or sphincter muscle all the time.
