This penis vacuum pump is designed with an easy finger pull for effortless pumping. The cylinder base provides a perfect vacuum seal. Water based lubricant is recommended to help slide your penis into the cylinder. This will also make a tighter vacuum seal, increasing the blood flow to your penis. Once your penis is inside the cylinder, gently pump to remove the air and create a vacuum. As the blood flow to your penis increases, you will achieve a larger and more sensitive erection. You can re-pump your erection, but your should avoid having it at full pressure for more than 10 minutes at a time. Pump gently to avoid injury. The quick release valve allows you to break the seal quickly, removing the pressure.
