Condoms can prevent semen from entering the vagina and play a role in preventing pregnancy. If condoms are used correctly, they can reduce the chance of HIV infection in high-risk sexual behaviors, but the failure rate is quite high.
Incorrect use of condoms
1. The use of condoms during sexual intercourse affects male pleasure, so condoms must be made very thin or unpopular with users. But the thinner the material, the more likely it is to rupture. According to a research report in the United States, even products that meet standards have a cracking rate. In addition, the thinner the latex film, the poorer its elasticity, and it is easy to slip off. No matter it is broken or sliding, semen leakage will enter the vagina, and Vaginal discharge will contact the penis, which will have an opportunity to spread HIV.
2. Condoms are made of a thin layer of latex, which is made of rubber and has a long storage time. When stored in a high-temperature environment, they come into contact with oils, acidic, alkaline substances, etc., promoting latex aging and making condoms prone to rupture.
3. There are four types of domestically produced condoms on the market in China, with a diameter of 35mm in the large size, 33mm in the medium size, 31mm in the small size, and 29mm in the extra small size. Employers should choose the appropriate model based on the actual size of their penis during erection. If the model is not suitable, it may become loose and slip, while if it is too tight, it may break.
4. There are currently counterfeit and inferior products on the market in our country. Vigorously promoting the use of condoms to prevent AIDS is different from the propaganda of sexual disorder. Many unmarried young people have Premarital sex and married people have given up the moral constraints of husband and wife to participate in sexual disorder. The demand for condoms has soared, and a large number of poorly made condoms may appear in the market. The result of using inferior condoms is an increased failure rate.
5. When using condoms, lubricating oil is often applied to the outside of the penis sleeve. Some people use the grease on their face to lubricate condoms, which usually contains mineral oils such as Vaseline. Tests show that when the penis sleeve contacts Vaseline, its brittleness will double within 60 seconds, so it is easy to break. Czech Republic knows that after anal communication is infected with HIV, homosexuals' anal communication behavior is significantly reduced. After that, homosexuals advocated the use of condoms for anal sex. Rational use of condoms is not good, and the AIDS virus infection rate must decline. However, contrary to expectations, the AIDS virus infection rate rose instead. Later, homosexuals used grease containing Vaseline to make lubricants, which increased the rate of condom breakage and HIV infection.
