Many men often wonder whether their sexual ability is “normal” and may feel anxious even with slight changes. In reality, sexual function is not determined by a single factor but is influenced by multiple aspects such as genetics, age, physical condition, mental state, and hormone levels.

What Determines Male Sexual Function?

1. Genetic Factors

Sexual function is partly influenced by genetics. Some men naturally have higher hormone levels and better physical fitness, which can result in stronger sexual ability from a young age. However, this does not mean that improvement through lifestyle and effort is impossible.

2. Age-Related Changes

Sexual ability is closely related to age. Generally, men reach their sexual peak between 20 and 30 years old, after which it may gradually decline. Not everyone experiences a noticeable drop, as maintaining good health and habits plays a key role.

3. Mental and Emotional Health

Long-term stress, anxiety, or frequent lack of sleep can disrupt hormone secretion, reducing libido and erection quality. Maintaining a healthy routine and managing stress are important for sustaining sexual function.

4. Hormone Levels

When hormone levels are normal and stable, sexual desire and performance tend to be healthy. If levels drop significantly, medical evaluation and timely intervention are advised.

5. Overall Health Status

Chronic conditions like diabetes, hypertension, or prostatitis can impact sexual function. Men in good health typically have stronger sexual ability. Regular check-ups and managing chronic illnesses are essential.

How Can Men Self-Assess Their Sexual Function?

1. Erection Ability

Being able to achieve a natural erection when sexually aroused and maintaining it long enough is a basic indicator. Occasional weakness or short duration may signal fluctuations in function.

2. Sexual Initiative

Being proactive about sex and still experiencing fantasies or desire reflects a healthy sexual mindset.

3. Response to Sexual Stimuli

Feeling aroused when seeing sexual images or a partner’s body can also indicate whether sexual ability is declining.

Simple and Effective Ways to Improve Male Sexual Function:

1. Massage the Navel Before Bed to Support Liver and Kidney Health

According to traditional Chinese medicine, the “Shenque” point (navel) is important for regulating kidney energy. Gently pressing the navel for 5–7 minutes daily before sleep can help improve circulation and kidney function, benefiting sexual health over time.

2. Wear Cotton Underwear to Protect Testicular Environment

Testicles function best at slightly lower than body temperature. Avoid tight or synthetic underwear to reduce overheating, which supports sperm production and hormone secretion.

3. Use Imagination as a “Booster”

Healthy sexual fantasies can stimulate the brain to release hormones that enhance sexual desire and responsiveness. Taking time to relax and mentally unwind is beneficial.

4. Massage the Groin to Promote Testicular Function

Gentle massage after bathing or before sleep for about 5 minutes can improve local circulation and sexual organ activity.

5. Penile Acupressure to Enhance Sensitivity

Lightly squeezing or rubbing the penis daily can improve nerve and vascular sensitivity, much like exercising muscles, leading to stronger and longer-lasting erections.

6. Regular Physical Exercise to Boost Overall Fitness

Exercise is the most natural way to enhance sexual function. Activities like running, swimming, or strength training improve cardiovascular health and hormone levels.

Sexual ability is not the sole measure of a man’s value, nor is it fixed. Through a healthy lifestyle, positive mental state, and regular exercise, most men can maintain good sexual health well into middle age and beyond.
