Have you ever unconsciously touched your crotch while working in the same position for an extended period? This is because our bodies instinctively stretch out shrunken, hardened testicles to prevent erectile dysfunction or broken penises. Stretching sensitivity approaches the core of the penis, which fashion massages cannot reach, and acts on the fatigued parts of the testicles, relaxing the core of the penis and eliminating stiffness in the penis and fatigue in the testicles. Even those with harder testicles can gently stretch them without strain, making this a pleasantly stimulating stretching menu.
