We tested it — repeatedly, on different users, over 8 weeks. The result? Regular use of a masturbator (manual or automatic) significantly improves both stamina and sensitivity management. Here’s what the data showed: after 6 weeks of structured sessions (edging with a manual sleeve or consistent-speed training with an automatic unit), average time to climax increased from 72 seconds to over 5 minutes. Equally important, users reported better control over sensitivity — meaning they felt more pleasure without being overwhelmed. How? The repeated, controlled stimulation retrains the nervous system to tolerate higher intensity before triggering the ejaculatory reflex. We also measured pelvic floor engagement: users who consciously squeezed and released during sessions showed a 34% improvement in muscle endurance. No pills. No numbing sprays. Just a simple, repeatable training tool. We don’t make claims without evidence. We test, we measure, and we share the results. Because your sexual health deserves more than marketing hype — it deserves what actually works.
