If a woman has sex, it is generally best to take contraceptive measures in advance. Ejaculation outside the body is unsafe, especially during the ovulation period, when there is a possibility of pregnancy. For safety reasons, it is best to take birth control pills. Compared with the damage caused by abortion, the side effects of birth control pills are negligible. However, it is best not to take emergency contraceptive pills more than three times a year, as birth control pills are very harmful to the human body. The biggest disadvantage of ejaculation outside the body is the low contraceptive rate. There are three main reasons for its failure: 1. During sexual intercourse, as sexual excitement continues to increase, the secretions of various glands in the male reproductive system begin to become active, and the secretions and part of the seminal vesicle fluid will overflow from the urethra and enter the female reproductive tract before ejaculation. This part of the secretion contains a certain number of sperm cells. 2. Many men do not have a good grasp of the exact time of ejaculation. They pull the penis out of the vagina too late, which can easily cause semen to remain in the vagina or at the external opening of the vagina. 3. Semen left around the female vaginal opening, on the male penis or other parts of the body may enter the female reproductive tract for any possible reason. Disadvantages of the withdrawal method of contraception 1. Its contraceptive effect is not ideal. Theoretically, expelling semen outside the female reproductive tract can prevent sperm from combining with egg, but in fact it is not reliable. First, it is difficult for many men to grasp the exact time to withdraw their penis. When orgasm comes, it is difficult to withdraw the penis in time, which often causes the initial small amount of semen to be discharged into the woman's vagina. The initial part of semen during ejaculation happens to contain the largest number of sperm, making it very easy to get pregnant. Second, the physiological laws of male reproduction and a large amount of practice have proved that sperm is not only discharged from the male reproductive tract during ejaculation. Often before ejaculation, when the male's penis twitches, that is, during continuous sexual excitement, accompanied by the contraction of the vas deferens, a small amount of sperm accumulated in the vas deferens will also overflow through the secretions in the reproductive tract. Therefore, even if one has good self-control and can accurately grasp the timing of ejaculation outside the body, he cannot control the sperm overflow that may occur before ejaculation. Therefore, the result may also lead to contraceptive failure. Moreover, both situations are difficult for men to detect. 2. This method can easily cause mental tension to both parties and affect the pleasure of sexual life. Because ejaculation interrupts the sexual intercourse process, it affects the entire process of a man's sexual response and has significant physiological and psychological effects on both parties. From the perspective of the reaction process of sexual life, men's sexual response process is completed under the control and regulation of the central nervous system cerebral cortex by physiological and psychological stimulation. When a man is sexually excited, the first symptom is an erection of the penis. As the sexual excitement gradually increases and reaches a high level, the erection of the penis will become harder until he reaches orgasm and ejaculation occurs. Since the erection is not sufficient in the early stages, it can easily disappear due to external interference or emotional changes. If this interference occurs repeatedly, it will affect the erectile function of the penis and cause obstruction. Because those who ejaculate outside the body must be vigilant and prevent the ejaculation of semen, they have a mental and psychological burden during sexual intercourse. This state of tension not only cannot meet the requirements of sexual excitement, but also affects the occurrence of sexual excitement orgasm. In addition, when orgasm occurs, ejaculation must be forcibly suppressed. Therefore, over time, dysfunction of the central nervous system and lumbar ejaculation center may occur, leading to symptoms of sexual neurasthenia. Clinically, there are indeed some patients with premature ejaculation and impotence who suffer from ejaculation outside the body. Because the experience and exploration of sexual life of newlyweds needs to follow normal physiological processes, the use of external ejaculation method is of no benefit to this practical exploration, so it is better not to use it. |
