Testicles are loose, erections are loose, and urination is normal. The only problem is the penis, which doesn't become completely loose like before; it remains in a somewhat rigid state.
With discomfort and lack of relaxation, the brain reprograms sexual stimulation from a "source of pleasure" to a "source of threat or suffering," reflexively shutting down the libido impulse. Your brain cannot feel sexual pleasure when it is in constant distress.
Avoid Uncontrolled Peaks and Valleys: Practices like binge-watching pornography and masturbation generate huge dopamine spikes followed by abrupt drops. This depletes your brain receptors and triggers the sympathetic nervous system, drastically worsening hard flaccid. Try fasting or drastically reducing these artificial stimuli.
The Pelvic Stress Reflex: Excess norepinephrine chronically activates the sympathetic nervous system ("fight or flight"). The human body responds to stress by clenching three main regions: the jaw (bruxism), the shoulders, and the pelvic floor.
Physical Restraint: Because the pelvis remains contracted for hours due to this state of neurological alertness, the muscles go into chronic spasm. They compress the penile blood vessels, preventing the penis from fully relaxing (resulting in the hard/rubbery appearance when flaccid).
They often exhibit a nervous system that is more sensitive to sensory and emotional stimuli.
Lack of attention causes individuals with ADHD to fall over and injure themselves, or to use masturbation to regulate themselves, as they also have poor dopamine regulation. Many also have sexual impulses, spend hours in uncomfortable positions, and in physiotherapy have difficulty perceiving their muscles contracting or relaxing.
