99% of people will fall into three sexual misunderstanding

Although you feel that you know a lot about gender knowledge, there will always be some small knowledge misunderstood by you. Some couples have sexual life long time but don’t know that they have many wrong ideas. What wrong ideas can’t be distinguished in their brains?

1. The use of contraceptives will not infect sexually transmitted diseases: in many contraceptives, only condoms have this dual function, which can be used for contraception as well as prevention of sexually transmitted diseases. Unless you use your own sex toy and sex doll you don’t have to worry about sexually transmitted diseases. The following is an analysis of the resistance of several contraceptives:

Oral contraceptives: there is nothing you can do to prevent sexually transmitted diseases.

Uterine cap, diaphragm: some protection of the fallopian tube, but the protection of the vagina is not enough.

Intrauterine contraceptive ring: this method of contraception actually increases women’s risk of sexually transmitted diseases, because pregnancy can be prevented without other protection.

Sterilization: reduces the risk of pelvic inflammation, but the risk of cervical and vaginal infections remains.

2. Oral contraceptives are harmful to the body: for women who smoke, oral contraceptives do have some harm. They may become victims of heart disease, stroke and other diseases, while women who don’t smoke don’t have to worry about it at all. According to the survey of medical institutions in the United States, women taking contraceptives are 40% – 60% less likely to have ovarian cancer than women not taking contraceptives, 50% less likely to have endometrial cancer, and less likely to have ovarian cysts. Oral contraceptives are also helpful in preventing pelvic inflammation, because regular medication thickens cervical mucus, which hinders the growth of bacteria. In addition, oral contraceptives can reduce the risk of ectopic pregnancy and help women with osteoporosis during menopause.

3. If you don’t ejaculate, she won’t get pregnant: if you are have sex during menstruation, you won’t get pregnant? the contraceptive method of external ejaculation is quite dangerous. Our partner in the “foreplay” in the secretion of lubricants (prostate fluid), there is part of the semen. Moreover, don’t put too much hope on the control ability of men. It’s hard to guarantee that everything is safe when you pull out the body before orgasm. In fact, most men have sperm leakage, and the number and mobility of sperm are enough to cause pregnancy. If you do not enter the vagina and ejaculate in the vulva, it is not impossible to be pregnant. Active sperm may enter the vagina and continue to move to the uterus. In addition, the general people think that menstruation should not worry about pregnancy. But the truth is: there is a real precedent of menstrual intercourse and pregnancy. This is due to irregular ovulation. Most women ovulate on the 14th day or so after menstruation, but if the ovulation period is advanced and sperm vitality is strong, it is likely to cause pregnancy. The average number of male ejaculation is about 300 million sperm. These sperm can survive in the female body for about 7 days. If the female ovulates in advance, it is very likely to be pregnant. Therefore, even during menstruation, necessary contraceptive measures should be taken.
