The pump may be used for temporary effects prior to, or during, masturbation or sexual activity. The pump is intended for use only on the penis area and should not be applied to any other part of the body, since it may cause injuries. The use of a pump is not only restricted to sexual pleasure purposes. Their use is often recommended by physicians for treating male sexual problems connected with ED. Improved blood flow to the genitals may be achieved through regular use of the device. To use the pump, add a few drops of water to the silicone sleeve at the bottom of the pump to ease insertion. Insert the penis into the silicone sleeve. The skin around the base of the penis will create a tight seal, and then pump out air to create a vacuum. As you pump, the seal gets tighter, the suction on your genitals becomes stronger, increasing the blood flow to your genital area, making it much more sensitive than usual. The first time you use a pump the feeling may be somewhat uncomfortable, but it is simply a matter of getting used to a new and unfamiliar feeling. If done correctly, you wonât damage your genitals. If you feel actual pain, itâs likely that the pump is sucking on sensitive skin above or below your target area (due to improper sleeve placement). Let the sore area calm down, reposition the pump and give it another try. Before using it, check with your doctor if you have a history of erectile health issues. Be careful. Use one pump at a time, do not keep pumping once youâve established a nice, strong vacuum, and release the vacuum if you feel any pain. Following these sensible precautions, your pump can heighten sexual pleasure well beyond the ânormalâ experiences of sex play./p&gtp&gtTo turn your device on/off, long-press the power button for 3 seconds. Insert your penis into the silicone sleeve. Check the seal against the skin to ensure proper contact. Press the function(s) button to turn it on and to cycle through the functions. As a vacuum is created between the skin and device, the sucking effect makes the penis area throb due to increased blood and skin tension. The pump allows complete control of the effect, and it can be stopped at any moment by releasing the vacuum or stopping the motor by long pressing the function(s) button. As you pump, the tissue around the selected area will swell, encouraging more blood to flow and making the skin much more sensitive. The tighter the seal and the more pumping you do, the greater the sensitivity. If you find you are experiencing any discomfort, stop pumping. It might take a while to get used to the sensations, but a pump should not cause any actual pain. DO NOT OVER-PUMP, AS THIS COULD LEAD TO INJURY AND POSSIBLE DAMAGE TO THE PUMP. The use of cock ring (sold separately) can help maintain the engorging of the penis when the desired size is reached. Gently remove the pump and enjoy the beautifully swollen, excitingly engorged look and amazing feel to your pumped area! Sex and masturbation are fine after pumping but remember to use lubricant, as the vacuum sensation can cause dryness./p&gtp&gtWARNING(S)/p&gtp&gtDo not use for more than 20 continuous minutes. Stop using the vacuum pump immediately if pain or discomfort occurs. Do not use under the influence of alcohol or drugs as they may impair the userâs judgment and increase the risk of injury. Misuse of the vacuum pump could cause injury./p&gtp&gt*Read user manual to learn the AI capabilities of this device./p&gt
