What is an erection?

An erection occurs when the penis hardens and enlarges due to increased blood flow. This increase allows the penis to straighten and separate from the body. Sexual stimulation or arousal is the typical cause of an erection. However, some people may experience spontaneous or random erections. Erections disappear after ejaculation, but they can also disappear without it.

What are the types of erections?

Erections are usually associated with sex. However, they can occur without sexual activity or during sleep. These are the three types of erections:

1. Reflexogenic erections occur when an object touches the genitals and causes arousal. This is probably the type of erection that most comes to mind, such as erections during masturbation or foreplay.

2. Psychogenic erections occur when you think about sexual memories or fantasies. This type of erection occurs without physical contact.

3. Nocturnal erections occur during sleep, most often during deep sleep.

How does Erections Work? 

An erection occurs when blood flow to the penis increases, causing changes in its shape and size.

An erection occurs in three phases:

• Soft or flaccid penis: This is the "normal" state of the penis, occurring in the absence of sexual arousal or visual, tactile, or imaginary stimulation. During this phase, blood flow to and from the penis is even.
• Swollen penis: Sexual stimulation causes the brain and nerves to modify the blood vessels and other tissues in the penis, causing more blood to flow into the penis than out. The penis begins to swell during this phase.
• Erect penis: The penis becomes erect when visual, imaginary, or tactile stimulation continues. The brain and nerves continue to send more blood to the penis and restrict its flow. The penis then becomes fully erect, allowing manual stimulation or vaginal, anal, or oral intercourse.

Various physical or psychological problems can prevent an erection from occurring or from lasting long enough for sexual activity.

Factors That Affect Erections
Various factors can temporarily cause erection problems. These include:

• Fatigue
• Alcohol or drug use
• Distractions
• Feelings of embarrassment
• Tension
• Discomfort with a partner

In addition to temporary causes of erectile dysfunction, medical problems can also cause short- or long-term erectile dysfunction.

For example, after treatment for prostate cancer, some people may develop erectile dysfunction (Trusted Source). However, it is still possible for these individuals to regain full sexual function.

How Long Can the Average Man Stay Erect?

An erection can last from a few minutes to several hours. There is no true average length of an erection. Generally, the average duration of male erection during intercourse before ejaculation is about seven minutes.

Several factors can influence the duration of an erection. Age, ejaculation, stress, or alcohol are examples of factors that influence erections.

Seek emergency medical attention if you have an erection that lasts more than four hours. An erection that lasts more than four hours is called priapism.

What causes a person to maintain an erection?
The way a person achieves and maintains an erection is extremely personal and unique to each individual. It's important to note that erection problems can occur with age or the onset of other health problems. Your healthcare provider can discuss your situation with you and develop a treatment plan if you feel your erections aren't strong enough or don't last long enough to enjoy sex.

In general, however, there are steps you can take to improve your erections. For example:

• Eat a healthy diet and maintain a healthy weight.
• Take steps to prevent or control high blood pressure, high cholesterol, and other chronic conditions that can affect your erection. Keep in mind that medications used to treat these conditions can also sometimes affect your erections.
• Exercise regularly. Most health experts recommend at least 20 to 30 minutes of exercise a day.
• Avoid drug abuse and tobacco. If you drink alcohol, do so only occasionally.
• Try to reduce or minimize stress.
