This gentle ,painless stretching causes the cells within the corpora cavernosa to pull away and split.Just like muscle buliding,during the cell healing process,healthy new cells are created,allowing your penis to become larger.And with a bigger corpora cavernosa,your penis can hold more blood,meaning you'll also enjoy bigger and harder erections! Instructions for use Lubricate the inner wall of the cylinder and yourself. Insert your penis into the cylinder. The cylinder should remain firmly pressed against the base of your penis to keep air from escaping. Slowly begin to work the pump. There will be a slight sensation as air is drawn from the cylinder. For beginners, it is important to start this process slowly to avoid discomfort. Remember to press the safety release valve if the vacuum becomes painful. Continue pumping/releasing air until you've found a level of vacuum suitable for you: the penis should look swollen, but should not hurt. Now make sure no air escapes (unless needed) and wait 20 minutes. You may need to pump further during this time to keep an appropriate amount of vacuum in the cylinder. Once the session is complete, you should appear thicker/longer and have heightened sensitivity. These results are effective for 24 hours, but you may experience permanent results through long-term use. We recommend 3-4 sessions per week. Note: 1: This product flange design, for penis movement more comfortable to obtain the best results, it is recommended to shave the hair on the penis, do not use silicone seal valve. The sealing valve will bind the penis body, blocking blood circulation, and the foreskin will not be able to slide freely up and down, causing the epidermis to rupture.
