At first, many people naturally have doubts, but this treatment method actually delivers noticeable results. By inserting fingers into the vagina and adjusting the pelvic alignment from the inside, it allows for deeper, more direct correction of muscle and pelvic balance. Stimulating the waist and hip joints from the outside simply can't achieve the same immediate effect. Internal stimulation directly targets deep muscles and joints, making the results significantly more effective. Furthermore, inserting an erect penis creates tighter contact with the vaginal walls, enhancing the quality of stimulation. As a result, the treatment offers immediate effects and a more natural, highly effective therapy experience.
