My take on why and what…
I sensed the rock hard erection immediately after some minutes the first try. I doubt it inflamed that fast.
I also, when going REALLY FAST with the thumbs, can create immediately the hot blood flush. That works everytime!
There is a mechanical reaction and it feels exactly like Janus explained.
A vacuum or “draw-in” is created inside my dick, that I NEVER were able to get with normal wanking or fast sex.
I clearly gained vein seize. I cleared up a “bad vein” and smooth muscle on my left side.
That said there seems to be a noticeable drop off in improvement after some time doing AM.
It feels like I need to go much longer and more intense to get the first week results like big hang etc.
It seems as if I reached 10/10 already. Even a week pause doesn’t give the initial long term PI’s.
I had the goal at first to grow monster veins after the first improvement but there is not much more happening.
I think hope’s explanation about the inflammation makes sense and is part of it.
It’s probably like with other PE that you have to manage the inflammation. Keep it going to some point and then let heal, rinse, repeat. IPR principles are well established.
I also think the TGC theory, at least some of it, applies with AM. The AM helps the “insides”(smooth muscles) to get to it’s full potential, “filling in”. The pressure on the Tunica then is optimal to have a 10/10 erection.
THERE IS NO DOUBT that Tunica can be a big limit to grow.
You would have to do AM for many hours at “high speed” in a fine tuned routine similar to a priapism to get a result.
I did AM for some days 2-5 times a day and I reacted strongly and then had to do a pause after some days when I reached negative PI ‘s!
Like with a clamping routine.
I’m pretty sure that it’s very hard to grow seize beyond your tunica limits with AM ALONE.
BUT combined with other PE prior it has the potential to be the go to exercise to fill tunica expansion in.
For example clamping and then AM after it. Clamping stretches the tunica and AM is able to edge a bigger size then normal wanking.
