What causes a lack of sustained rigidity in the penis?

Many men encounter various problems during sexual intercourse, such as some men exhibiting a non-lasting erection during the process, even though they can achieve an erection. This may be due to premature ejaculation, psychological reasons, or unhealthy lifestyle habits, which lead to the male's penis erection not being long-lasting.

1. Premature Ejaculation

Non-lasting erection of the penis may be due to premature ejaculation. Premature ejaculation is a common ejaculation disorder, and clinical factors may include excessive sensitivity of the glans penis, neurotransmitter disorders such as 5-hydroxytryptamine imbalance, and the presence of erectile dysfunction, leading to urogenital diseases such as prostatitis or thyroid disorders. Psychological factors may also contribute to similar manifestations.

2. Psychological Reasons

Psychological reasons can also lead to non-lasting erections for men. Low desire, anxiety, and depression may interfere with the brain's erection signals, resulting in weaker and inconsistent signals, causing the erection to be unsustainable and the penis to soften quickly. If the emotional connection with the partner is poor and good sexual pleasure is not achieved during sexual activity, it can also lead to non-lasting hardness of the penis.

3. Unhealthy Lifestyle Habits

Unhealthy lifestyle habits can also affect male sexual function. For example, staying up late or lack of sleep for extended periods can significantly affect the body's endocrine function, further affecting the hardness and duration of the penis's erection. If a person frequently consumes spicy, fried, or other harmful foods, it can have a significant impact on the body over time, leading to non-lasting hardness of the penis's erection. Additionally, excessive masturbation can also affect the hardness and durability of the penis's erection.
