Preliminary data on sexual dysfunction in men.

Sexual dysfunction in men is a disorder of sexual ability.

Sexual dysfunction has a variety of disorders and affects:

Libido;
Achieving or holding sexual arousal (erectile dysfunction or impotence);
Ability to ejaculate;
Achieving an erection without deformity of the penis;
Achieving orgasm.
Sexual dysfunction can be caused by physical or psychological factors.

Often, both factors cause sexual dysfunction. Physical (somatic) disorders lead to psychological disorders, which in turn exacerbate somatic disorders. Sometimes men force themselves to have quality sex, or feel such pressure from their wives. Failure to have quality sexual intercourse can lead to psychological distress (fear of possible failure). Fear of possible failure is more disturbing. This further reduces the ability to enjoy sex in men.

The most common sexual dysfunction is ejaculatory dysfunction. These disorders include:

Premature ejaculation (before or after the penis enters the vagina);
Ejaculation into the bladder (retrograde ejaculation);
Inability to ejaculate (aneagulation).
Erectile dysfunction is more common in middle-aged and older men. Some men also experience a decrease in libido.

Normal sexual ability in men
In men, normal sexual ability is a complex system in which body parts and spirit are involved. The nervous, circulatory, and endocrine systems combine with the psyche to produce a sexual reaction.
Libido is the presence of a desire to have sex. It is called by thoughts, by words, by sight, by smell, or by touch. Libido initiates arousal, which is the first stage of the sexual reaction.
Then sexual arousal begins. The brain sends a nerve signal to the penis through the spinal cord. The arteries there dilate, filling and enlarging the porous body with blood. As a result, the veins that carry blood out of the penis are crushed and the blood in the penis stagnates. In this way, the penis enlarges and thickens. It also increases muscle tension throughout the body.
In the next plateau, the range of motion and muscle tension increase.
The orgasmic stage is the culmination of this sexual arousal. During orgasm, muscle tension throughout the body increases further; the pelvic floor muscles contract, then ejaculation begins.
Ejaculatory nerves occur when the male sex organs - the seminal vesicles, prostate gland, testicles and seminal vesicles - contract. These contractions push the sperm into the urethra. Sperm are expelled as a result of the contraction of the muscles around the urethra. At this point, the bladder shortens and prevents sperm from entering the bladder.
Although ejaculation and orgasm occur simultaneously, they are both separate processes. Sometimes ejaculation occurs without an orgasm. Orgasm can also occur without ejaculation. This can occur during puberty or under the influence of certain medications (such as antidepressants) or after surgery (for example, when the colon or prostate gland is removed). Orgasm is usually very pleasant.

At the end of the day, the body returns to a state of inactivity. After ejaculation or orgasm, the penile arteries narrow, the smooth muscles of the penis contract, resulting in a decrease in blood pressure in the penis and a softening of the penis (erection ends). After an orgasm, it takes some time to get an erection again. In young men, this is usually around 20 minutes, and the difference in erections between men increases with age.
Erectile dysfunction is more common in middle-aged and older men. Some men also experience a decrease in libido.

Psychological causes of sexual dysfunction
Anger at one's sexual partner;
Discomfort;
Lack of understanding or interest in each other with a sexual partner;
Dissatisfaction with one's sexual life or sexual partner;
Feelings of guilt;
Sexual embarrassment;
Fear of possible failure;
Previous incidents of sexual experience.
Sexual activity and heart disease
Sexual fatigue is usually less than moderate or severe physical activity, so sex is usually not a risk factor for men with heart disease. However, the risk of myocardial infarction is higher during sexual intercourse than at rest.

In any case, a man with a heart condition who is having sex should consult a doctor. Sex is usually safe if the disease is mild, asymptomatic, and the blood pressure is high. If a man has had a myocardial infarction, he should ask his doctor when he can continue having sex. According to the American Association of Cardiologists, one week after a myocardial infarction, it is possible to continue sexual intercourse in the absence of pain and shortness of breath in the heart.

Taking sildenafil, vardenafil, avanafil, or tadalafil can be dangerous for men taking nitroglycerin. Because these drugs can lower blood pressure to dangerous levels.
