How big can my penis get with a penis pump?

Many men sometimes think about the size of their penis or experience difficulties getting an erection during sex. This is completely normal, but it doesn’t mean you have to accept the situation as it is. With a penis pump, you can achieve a larger and fuller penis and maintain your erection for longer.

Using a penis pump can make your penis up to 20% larger

After just one session with a penis pump, the penis can typically become 5–10% longer and 10–20% thicker in girth. However, the effect is temporary and lasts from a few minutes up to a couple of hours. Men who use a penis pump regularly, for example 4–5 times per week over several months, may sometimes experience a long-term increase.

Some studies and user experiences indicate a potential size increase of 5–10% in length and 10–15% in girth after 6 months of consistent use. Since the penis pump primarily expands the blood vessels and erectile tissue, the girth is usually affected more than the length. Many users report that the girth increase tends to be more permanent than the length increase, although some length growth can also occur with regular use.

How a penis pump works

A penis pump creates a vacuum around the penis, which increases blood flow and causes it to swell. Immediately after use, the penis often feels both longer and thicker. With regular use, it can also improve endurance and, in some cases, contribute to long-term improvement in erectile function.

There are two main types of penis pumps: air-based and water-based.

Air-based penis pumps

These create a vacuum by drawing air out of a cylinder using a manual or motorized pump. The pressure that forms causes the blood vessels to expand and blood to flow into the erectile chambers, resulting in a larger and harder penis.

Water-based penis pumps

These are filled with warm water before inserting the penis into the cylinder. By pumping, the water is expelled and a vacuum is created, which increases blood flow even more than with air-based pumps. Water provides a more even pressure distribution that is effective and gentle on penile tissue.

Both types can provide a temporarily larger penis and improve blood circulation, but water-based pumps have gained a reputation for being slightly gentler and providing better long-term results.

Use a penis pump in 3 simple steps

1. Maximize the sensation with the right preparation

To use a penis pump effectively, you need to create the right conditions. A water-based lubricant improves the seal between the pump and the skin while reducing friction, making the entire experience much more comfortable. If you have a lot of pubic hair around the base of the penis, it’s a good idea to trim it, as it can affect the quality of the vacuum created.

Taking a warm shower or bath before use can help dilate the blood vessels, resulting in an even stronger effect.

2. Pump gradually for the best results

When you’re ready to start using your penis pump, insert your penis into the cylinder while it is in a flaccid or semi-erect state. Slowly build up the vacuum by pumping manually or by starting the electronic pump on a low setting. The pressure should be noticeable but never painful. Once the penis has reached its maximum fullness, stop pumping and let the vacuum remain for 10–15 minutes. If you’re using a water-based penis pump, you can enhance the effect by keeping the pump under water before creating the vacuum.

Remember to take it slow – if you build up the vacuum too quickly, it can cause pain and discomfort.

3. Release the pressure and maintain the effect

When the session is over, slowly release the pressure using the release valve so that blood circulation returns to normal. If you want the enlarged effect from using a penis pump to last longer, you can immediately put on a penis ring at the base after pumping. This helps keep the blood in the erectile tissue, allowing you to maintain a larger penis for a longer period of time.
