My boyfriend's penis becomes soft after being hard for a while, what's going on?

In sex life, men often play a leading role, and the completion of the entire process of sex life depends on the hardness of the male penis. However, in life, some men's penises seem to be very weak, and they become very soft after being hard for a short time, which is unacceptable to women. So the question is, what is the reason for this situation of men's penis?

"Impotence" is the former name of "erectile dysfunction (ED)". In 1992, after discussion by relevant experts, the National Institutes of Health of the United States decided to replace the term impotence with erectile dysfunction. Erectile dysfunction (ED) refers to the persistent inability of the penis to achieve and maintain an erection sufficient for satisfactory sexual intercourse in the past three months; ED is one of the most common sexual dysfunctions in men. Although ED is not a life-threatening disease, it is closely related to the patient's quality of life, sexual partner relationship, and family stability, and is also an early warning sign of many physical diseases.

Causes

The occurrence of ED is not only affected by physical diseases such as age, cardiovascular disease, diabetes and hyperlipidemia, as well as psychological and environmental factors such as sexual partner relationships and home conditions, but also by bad living habits, drugs, surgery, race, culture, religion and socioeconomic factors.

1. Age

Current research suggests that age is the strongest independent factor among ED-related risk factors. As age increases, the serum androgen level decreases significantly, which may be the direct cause, but there is no research result proving that there is a significant relationship between the decrease in serum free testosterone and ED. In addition, as age increases, the structure of the penis tunica albuginea and corpus cavernosum changes, which may lead to a decrease in venous blood return capacity, an increase in the prevalence of cardiovascular and cerebrovascular diseases, hypertension, diabetes, and the treatment of these diseases, all of which damage the penis' erectile function to varying degrees, and this trend also increases with age.

2. Cardiovascular disease

Cardiovascular disease is the main somatic disease associated with ED, including atherosclerosis, peripheral vascular disease, hypertension and myocardial infarction. Cardiovascular disease causes arterial ED by affecting the arterial blood supply to the corpus cavernosum. Some studies have also found that ED may be the primary manifestation or "warning signal" of cardiovascular disease.

3. Diabetes

Diabetes can affect erectile function by affecting the autonomic nervous system, peripheral vascular system and psychoneural system. The severity and prevalence of ED are significantly related to factors such as age of diabetes, type of diabetes, blood sugar control, diabetic neuropathy, diabetic nephropathy and hypertension.

4. Abnormal blood lipid metabolism

The role of hypercholesterolemia in sexual dysfunction is controversial. One study showed that men with total cholesterol (TC) greater than 240 mg/dl had a 1.83 times higher risk of ED than men with TC less than 180 mg/dl. In the MMAS (Massachusetts Aging Male Study), high-density lipoprotein was negatively correlated with the prevalence of ED.

5. Chronic prostatitis

Some patients with chronic prostatitis have symptoms such as premature ejaculation, loss of libido, erectile dysfunction and ejaculation pain. The mechanism of sexual dysfunction caused by chronic prostatitis is unclear. Most scholars believe that anxiety, depression, inferiority, loss of energy, fatigue, suspicion and insomnia are the main causes. The recurrence and non-healing of long-term testicular swelling and pain, perineum and penis discomfort, lower urinary tract symptoms, etc. also increase the psychological burden of patients. Since the sexual dysfunction of most patients with chronic prostatitis is caused by psychological factors, in addition to drug treatment, more psychological counseling and treatment are needed.
