The efficacy of condoms?

Condoms can prevent many diseases, so users can avoid many dangers, so many people call condoms "condoms" and "condoms". So, what's the use of condoms? 1. Contraceptive effect. If you don't want to get pregnant, or you can't get pregnant because of illness, then pregnancy is a danger. Using condoms for contraception, semen is discharged into the bag to prevent it from entering the vagina and uterus. Sperm naturally cannot combine with eggs and become pregnant. This method is not dangerous, has no contraindications and does not require a doctor's prescription. 2. Prevent sexually transmitted diseases. This function of condoms is also the reason why condoms are more and more favored by people. For all kinds of sexually transmitted diseases, such as common mold, trichomonas infection, gonorrhea, syphilis, and the frightening super cancer-AIDS, condoms can keep them out of the body, which is the simplest and most effective way to prevent sexually transmitted diseases. 3. Prevent cancer. The occurrence of common cervical cancer in women is closely related to sexual contact. Young sexual behavior, frequent abortion, too many sexual partners and the stimulation of penis scales are all factors that induce cervical cancer. New research shows that the occurrence of cervical cancer is related to human herpesvirus infection, and the incidence of cervical cancer in patients infected with this virus is significantly higher than that in normal people. Condom has the function of isolation and barrier to the above factors, which can avoid infection, spread and reduce bad stimulation, thus reducing the occurrence of cervical cancer. 4. Prevent premature ejaculation. There are many reasons for premature ejaculation, but one of the important factors is that some men's ejaculation stimulation threshold is too low-that is, the stimulation level leading to ejaculation is too low. In other words, these people are too sensitive to sexual stimulation and will be "like a note" when touched, resulting in both men and women unable to achieve sexual satisfaction. Using condoms not only reduces the sensitivity of sexual contact, but also makes the spirit more relaxed, thus obviously prolonging the ejaculation time. Although condoms have many unique functions, many people are still reluctant to use them. Some people think that using condoms, such as itching through clothes, will reduce pleasure. In order to avoid this weakness of condoms, the new generation of condoms has been improved, such as better texture, ultra-thin elasticity and more novel style. Some backs are also designed with ridges (slightly convex parts) to enhance the stimulation effect. Condom surface can be coated with some contraceptive gel to improve lubricity (vaseline and other oils are not suitable) and avoid drying. Some people don't want to use condoms because they feel uncomfortable: for example, they must be worn on an erect penis before ejaculation; Must stop before after ejaculation, penis weakness. They are afraid that these processes will interfere with the natural completion of sexual life. In fact, habit becomes nature. As long as the mind is relaxed and the atmosphere is pleasant and harmonious, it will be regarded as an interest. If these processes are done casually and naturally, it will not affect sexual pleasure. Moreover, the use of condoms can also ease the fear of pregnancy without affecting sexual satisfaction. However, in order to ensure the efficacy of condoms and enhance sexual pleasure, users must pay attention to the selection of suitable condoms, check whether there is leakage before use, and leave a small bag in front. If you accidentally leave the condom in your vagina (mostly because the model is too big or after ejaculation didn't take it out in time), don't panic, just take it out in time. However, in order to ensure the success of contraception, we should take 1 "morning after pill" in time. It should be noted that a small number of people (both men and women) have latex allergies, and this group of people should not use condoms. Pure vaginal dry red is not allergic, and it can be solved by applying some lubricants such as contraceptive gel.
