First, make sure the penis pump is equipped with batteries . Apply some lubricant to your penis and place the cylinder all the way over your penis. Make sure that the edge of the cylinder press gently against your skin. Turn on the penis pump to create a vacuum in the cylinder . If necessary, use the remote control or the buttons on the pump to regulate the pressure in the cylinder if possible. The pump ensures that a lot of blood is pumped into the penis, which gives you an erection and makes your penis longer and thicker. Release the vacuum in the cylinder after use with the valve. It is recommended not to use the penis pump for more than 15 minutes at a time. If you experience pain during use, stop immediately and consult your doctor in an emergency. Tip: Before using the penis pump, put a cock ring around the rim of the cylinder. You can roll this around your penis just before removing the cylinder to enjoy the erection for as long as possible.
