- Loss of gains when combined with weaker erections, especially loss of girth.
The theory: Let's go through the motions here. If the erection is hard, then that means the smooth muscle is relaxed enough to press against the tunica (and essentially create a suction so blood can't leave the penis). If the erection is weak, a few things could be happening . . . but it most often means the smooth muscle isn't relaxed enough to press against the tunica and cause an erection or there isn't enough smooth muscle to do so (
The Penis as a Vascular Organ).
According to this new theory, when gains are made, two things can happen:
- Both the tunica and the smooth muscle have to be pushed to a new limit
- Either the tunica or the smooth muscle was already pushed to a new limit, and the other one "catches up" causing the gain
Similarly, when gains are lost, either both fall from their previous limit or just one does (either the tunica or the smooth muscle). If a loss of gains occurs in conjunction with weaker erections, then hypothetically the smooth muscle has decreased while the tunica has stayed the same - and thus the smooth muscle can't relax enough to press against the tunica. A loss of gains can occur in either short-term or long-term.
- A short term loss of gains is a negative PI. It's caused by overtraining. We can assume that similar to skeletal muscle, when the smooth muscle is overtrained, it experiences fatigue and can't be pushed to the fullest - and thus can't sustain maximum erections.
- Long term lost of gains due to taking a break or not cementing gains. If erections are weak, then presumably more tunica gains were cemented than smooth muscle gains (thus causing a gap and weaker erections).
Note: According to this theory, weak erections can get tricky real quick. If the tunica enlarges and the smooth muscle doesn't, this creates a "gap" that needs to be filled. This is where the theory gets tricky - are you experiencing weak erection because of muscle fatigue or because you need to catch your smooth muscle limit up to your tunica limit?
Further note: Perhaps a way to test this would be that if your penis is the same size when it's at its peak, then your smooth muscle didn't decrease (or become fatigued) and thus the tunica just enlarged. This might be hard to test, as if the smooth muscle can't relax enough to cut off blood from leaving the penis, then there is no way to reach the "peak."
