The 4 contraceptive methods that are most likely to cause "life"

　　“"Love" is a physical sport that mature men and women are passionate about.

　　“"Love" can destroy stress and relieve tension；

　　“"Love love" can burn calories and get slimmer；

　　“"Love love" can keep you young and prolong your life.

　　However, for people who have no plans to have children for the time being, in addition to the above characteristics, "love" also lurks the danger of causing "human life". A survey report on contraception among young people showed that only 23% of the respondents clearly understood information about contraception, while 77% of the respondents did not understand or were confused about contraception. As many as 55% of the respondents believe that in vitro is a safe method of contraception, and 23% think that the safe period is a safe method of contraception. Both of these are very unreliable contraceptive methods that can easily cause unwanted pregnancy. In addition, 54% of Chinese respondents said they had had unprotected sex.

　　One of the most unreliable - in vitro ejaculation contraceptive method

　　In vitro ejaculation means that during sexual intercourse, when a man feels the sensation of ejaculation, that is, before ejaculation, he pulls his penis out of the vagina and ejaculates the semen outside the vagina so that the sperm cannot meet the egg, thereby achieving the purpose of contraception.

　　Disadvantage 1: Imminent ejaculation and ejaculation are a continuous action, and the time between the two is extremely short. Most men cannot accurately grasp the timing, so that when they are about to reach orgasm, they cannot withdraw the penis from the vagina in time, so that the initially ejaculated semen is discharged into the woman's vagina. This part of the semen contains the largest number of sperm, so it is easy to lead to pregnancy.

　　Disadvantage 2: Men often have a small amount of sperm entering the vagina before ejaculation. The sperm at this time is the sperm accumulated in the vas deferens. During sexual excitement, as the vas deferens contracts, it is first discharged into the urethra, and then overflows into the vagina along with urethral secretions.

　　Disadvantage 3: Pulling the penis out of the vagina in time requires the man to grasp the "heat" "just right". This makes both men and women nervous because they pay too much attention to the ejaculation time, making the sexual intercourse unsatisfactory, and even causing sexual intercourse over time. nerve weak.
