You’re missing the main point of this. Proper PE WILL relax the smooth muscle to a greater degree than anything else except things like Viagra and Cialis. This is why proper PE also leads to great EQ, relaxed smooth muscle and great EQ go hand in hand.
When you are in the “zone” with your PE, you see heavy and long flaccid, that IS Super Relaxed smooth muscle, hence the term SRR or Super Relaxation Response. I get the same thing when I take Cialis.
The difference is when I get that from PE, its a good chance I have also stimulated growth, whereas with Cialis or Viagra aren’t stimulating growth, just relaxing smooth muscle.
I believe I address smooth muscle in my EQ thread.
