How to wear and use the mamba boxed for the best results
Getting comfortable with how to use penis extensions makes all the difference. Warm the sleeve briefly in water to enhance that realistic feel, then fit it per the base-ring system before penetration. The hollow design means the wearer still feels stimulation from those internal sensation nodes — couples’ intimacy stays mutual and engaged. Keep a water-based lubricant nearby for comfort.
