Speed and rhythm consistency are neurological skills — the same kind of finger coordination musicians or surgeons train. They become automatic with about 2 weeks of regular practice (10–15 min/day).
The yellow glow shows the zone you should focus on. The pink curve below the anatomy is your live arousal trajectory — watch the valleys and peaks, that's the shape of a real build.
Real-world note: every woman responds differently. This trains the foundation (steady rhythm, zone awareness, build/edge phases). It's a skill base, not a prescription.
