When it comes to maintaining your blow-up sex doll, proper inflation and deflation are essential steps to ensure its longevity. Using a pump designed specifically for inflating sex dolls, carefully fill the doll to the recommended pressure level. Overinflating can put unnecessary strain on the material, leading to potential tears or leaks. On the other hand, underinflation can result in a less pleasurable experience and may cause creases in the material that could become permanent over time.
