Squeeze control techniques for premature ejaculation and common misconceptions about male genital morphology

However, premature ejaculation is not incurable. One effective method advocated by Masters and Johnson is the "squeeze technique." At the onset of genital contact, the woman intermittently squeezes the penis, placing her thumb on the glans and her index and middle fingers on the side of the coronal sulcus opposite her thumb, applying slight pressure for about 4 seconds to control ejaculation (the man can tell the woman how much pressure to apply). After about 30 seconds, intercourse begins. In the early stages of premature ejaculation treatment, the man should apply the squeeze whenever he feels the urge to ejaculate; as the condition improves, the frequency will decrease. This technique can also be practiced alone, controlling ejaculation during masturbation. To control ejaculation during intercourse, it must be practiced together with a partner. There are some misconceptions about the genitals, two of which are worth noting: The larger the penis, the stronger the sexual function. Regardless of erection, body size is directly proportional to penis size; the taller a person is, the larger their penis tends to be. Masters and Johnson investigated the average penis size; the average length of a flaccid penis is 9.5 cm. This study also showed that smaller penises can increase in length by two times or more when erect. A larger penis only increases in length and size by half when erect. Generally speaking, the length and size of an erect penis should be similar. They also found that penis size is unrelated to the ability to achieve orgasm or successfully control ejaculation. Although some smaller penises are still relatively small when erect, the vagina, when sexually stimulated, can accommodate them appropriately, regardless of penis size. They noted that due to visual angles, people often mistakenly perceive their penis as shorter. Infertility. When a female doctor mentioned her own infertility, she said, "Infertility damaged my self-esteem, violated my privacy, impaired my sexual function, and in short, traumatized me both physically and mentally." Men rarely talk about how infertility affects them. However, as one infertility treatment expert said, precisely because they remain silent, their emotions are no less hurt. From a medical perspective, infertility is defined as the inability to conceive after one year of trying after marriage, which affects about 20% of couples. More and more couples are now seeking treatment. They no longer accept traditional advice such as "adopt a child," "remarry," or "face reality, it's God's will." When a couple seeks help for infertility, their primary concern is finding the cause. In the past, infertility was often attributed to female factors, but many conditions can affect male fertility. Generally, about one-third of infertility cases are related to the male, one-third to the female, and the remaining one-third are due to factors in both partners. In women, infertility is often caused by pelvic inflammatory disease, endometriosis, endocrine disorders, or as a result of sexually transmitted infections. Infections caused by Neisseria or Chlamydia are particularly prone to causing inflammation and scarring of the upper reproductive tract, such as the fallopian tubes. The causes of female infertility vary, ranging from inability to ovulate normally, or the inability of the egg to be transported to the uterus, to a lack of a suitable environment for implantation of a fertilized egg in the endometrium. Female infertility can also be caused by the effects of previous contraceptive methods, leading to prolonged conception. One known cause of male infertility is varicose veins in the scrotum. Whether this causes sperm abnormalities, reduced motility, or decreased sperm count is uncertain. One theory suggests that increased blood flow to the testes raises scrotal temperature, thus affecting sperm production. Endocrine disorders such as thyroid dysfunction and erectile dysfunction can sometimes cause infertility. Some infertility is also related to certain chemicals, but the extent of this relationship is unclear. Contrary to some views, aging itself does not affect male fertility. Although with aging, only a small percentage of sperm remain viable, requiring multiple attempts to fertilize an egg, this only becomes a problem when a significant percentage of sperm are abnormal or have severely reduced motility. In many cases, there are numerous methods to improve the quantity and quality of sperm production.
