1, the harm of male sexual intercourse interruption
When the lust is strong, in order to prevent "accidents", some men have to stop in time, choose to interrupt sexual intercourse and end their sexual life in a hurry. As everyone knows, this will not only affect sexual pleasure, but also cause harm to the body.
In medicine, sexual intercourse interruption refers to a way that when men feel that they are about to ejaculate, they pull Tintin out of women's private parts and shoot semen out of women's bodies. Interruption of sexual intercourse is the oldest contraceptive method, which was first seen in the Hebrew Bible in the West more than 2,500 years ago. Before the invention of modern contraceptive measures, it was once popular in Europe and other places. Interrupting sexual intercourse, as a contraceptive method, does not need any cost, and the method is simple, but it has many hazards.
First of all, interruption of sexual intercourse is prone to sexual dysfunction. Male sexual life is a natural process. After sexual stimulation, Tintin became congested and erect. With the continuous accumulation of sexual excitement, semen is gradually transported to urethra and prostate. At this time, the bladder neck and external urethral sphincter contract, and then ejaculate, reaching orgasm, resulting in great physical and mental pleasure. This natural and pleasant process comes to an abrupt end near the climax, which will destroy the scenery and have a bad influence on both sides' psychology. Men will make the central nervous system and lumbosacral ejaculation center involved in sexual life appear obstacles, which will lead to no ejaculation, and some even have erectile dysfunction.
Secondly, interruption of sexual intercourse can easily lead to contraceptive failure. Interrupting sexual intercourse is a contraceptive method with high failure rate. Some research data show that the failure rate of contraceptives is about 0.3%, the failure rate of female intrauterine devices is about 0.6%, the failure rate of condoms is about 2%, and the failure rate of interrupted sexual intercourse is 4%. In some studies, the failure rate of interrupted sexual intercourse is as high as 15%-28%. The reasons may be: during sexual life, a small amount of semen may have entered the female private parts before male ejaculation, and the sperm concentration of this part of semen is high; The timing of interrupting sexual intercourse is sometimes difficult to grasp, so a small amount of semen may be shot into the female private parts; After sexual intercourse is interrupted, the man touches the female private parts with his hand or Tintin, and some sperm may enter the female reproductive tract, leading to contraceptive failure. Once contraception fails, it may cause certain harm to both men and women.
Finally, it leads to tension in the relationship between partners. The interruption of sexual intercourse destroys the natural process of sexual life, which may have a negative impact on the psychology of both parties, and even cause sexual apathy, affecting the quality of sexual life; Couples may also misunderstand each other because of contraceptive problems, thus affecting their feelings.
Therefore, it is recommended that men try not to use interrupted sexual intercourse. Of course, if there are no other effective contraceptive measures, you can also consider temporary emergency, but don't use it frequently.
2. Feasible contraceptive methods
Condom is the least harmful contraceptive method, and most people use condoms for contraception. However, some people think that putting a condom on Tintin will prevent Tintin from directly contacting women's private parts, thus affecting the pleasure of sharing a room. So, without condoms, what other methods can be used for contraception?
oral contraceptive
Oral contraceptives are sex hormone drugs, which will definitely have an impact on some women's desires. However, this influence is often two-way, that is, some women often have decreased desire or sexual dysfunction; However, other women show enhanced loveliness and sexual ability after taking the medicine. The key lies in their knowledge and attitude towards contraceptives. For most women, oral contraceptives have little effect on sexual life.
rhythm method (of contraception)
The safety period is divided into pre-ovulation safety period and post-ovulation safety period. The period from the day when menstruation is clean to the day before ovulation is the safe period before ovulation. The safe period after ovulation is from the first day after ovulation to the day before the next menstrual cramp. The safe period after ovulation is safer than that before ovulation. This is because some women are sometimes affected by environmental changes and emotional fluctuations and ovulate in advance, so that the safety period before ovulation will be shortened unconsciously, so that the safety period before ovulation is not very safe.
Three days before ovulation to two days after ovulation is a dangerous period, and other days are a safe period. But the calculation of safety period is easier for women with regular menstrual cycle (see the calculation of ovulation day); People with irregular cycles are not suitable for this method. The rate of unintended pregnancy within one year is 20%.
Use female private parts ring
It is a soft and transparent rubber contraceptive, which can slowly decompose hormones, estrogen and xanthone. The ring in a woman's private parts is about two inches in diameter. Put it in the private parts of women, it has contraceptive effect. Every female genital ring can play the role of contraception within one month.
The success rate of female genital ring contraception is similar to hormone contraception, and the contraceptive rate reaches 92%. In other words, only 8 out of 100 women who use female genital rings will get pregnant unexpectedly.
The side effects of female genital ring include: female genital infection, scratching with oxygen, abnormal bleeding, headache, chest tightness, weight gain and loss, dizziness, vomiting, abdominal distension, decreased desire and depression. Women who use female genital rings are more likely to suffer from heart disease and stroke than other women.
Diaphragm and uterine cap of female private parts
The diaphragm of female private parts is easy to shift due to improper use, resulting in unpleasant sexual life; The uterine cap is firmly fixed on the cervix and will not shift due to the expansion of female private parts, so it has little effect on sexual life. It is a safe and reliable contraceptive for women. When in use, it is placed on the top of female private parts to cover the cervix, so that the sperm of female private parts cannot enter the uterine cavity, thus achieving the purpose of contraception.
Generally, the diaphragm of female private parts is taken out 8 ~ 12 hours after sexual intercourse. Sperm live in female private parts for 8 ~ 12 hours. If taken out too early, some sperm can still move in women's private parts, which can enter the cervix and uterine cavity and lead to pregnancy, and contraception may fail. Placement time should not be too long, not more than 24 hours, so as not to stimulate the wall of female private parts, so that too much secretion may cause discomfort or infection.
3. The difference between physical interruption and sexual interruption.
Internal ejaculation: Internal ejaculation, commonly known as internal ejaculation, refers to the phenomenon that men ejaculate into women's private parts or anus during sexual activities. In vivo ejaculation is the most basic mating method in biology, and ejaculation in a woman's private parts may lead to her pregnancy.
Interrupting sexual intercourse: Interrupting sexual intercourse is a very common contraceptive method, which means that in sexual life, when a man is about to ejaculate, he will take out Tintin in time to make the semen shoot out of the woman's body.
