Will starting sex too early do harm to your health? ….. In order to answer the above doubts, today, the family doctor will come to give you some knowledge about popular science!For these reasons, I think black ant king The situation is still optimistic, and the market is still in a blue ocean stage. http://herbal-hall.com/Black-Ant-King.html

　　What harm will it bring to women if they start having sex too early?

　　If a female friend starts having sex too early, it may bring the following potential hazards and health problems, including:

　　1. Inflammatory infection is more likely to occur: the reproductive tissues and organs of underage women may not be fully developed, and they may start sexual life too early, which is more likely to be infected by germs, causing diseases such as pelvic inflammatory disease, vaginitis and urethritis.

　　2. It is more prone to reproductive organ damage: It is also due to the underdeveloped reproductive organs of underage women, who start sex too early. If one is too hard, it will be more likely to cause internal and external pudendal damage.

　　3. Increased risk of contracting sexually transmitted diseases: Sexual activity is the most common route of transmission of sexually transmitted diseases. Starting sexual life too early will greatly increase the risk of women being infected with sexually transmitted diseases such as AIDS, syphilis and gonorrhea.

　　4. Bring great psychological and emotional pressure: Due to immature mental development, premature sexual life may bring psychological and emotional pressure to women. This includes the confusion of self-values, emotional instability, interpersonal problems and so on.

　　5. Increase the risk of pregnancy and ectopic pregnancy: Due to the lack of sexual knowledge among minors, premature sexual life may lead to pregnancy or ectopic pregnancy without proper contraceptive measures.

　　When is a good time for a woman’s “first time”?

　　From a physiological point of view, women’s reproductive tissues and organs are generally fully developed at the age of 17~18, and the specific time varies from individual to individual. In other words, under normal circumstances, women can have their first sexual life after the age of 18. But in fact, physical maturity cannot be used as a criterion to judge when to start “the first time”. Specific to every woman, it is more important to see whether her psychological development, sexual knowledge reserve, cognition of love and other factors match. As long as everything is ready, it is the best “first time”.

　　What preparations should I make before I start having sex?

　　1. Carry out self-health examination: ensure the health of both men and women, and confirm that neither of them has any sexually transmitted infections or other gynecological diseases.

　　2. Master the correct contraceptive measures: determine whether you are ready for contraception and choose the contraceptive method that suits you to prevent the adverse consequences of unintended pregnancy.

　　3. Be emotionally prepared: Sexual behavior is not only a physiological behavior, but also involves emotional and psychological aspects. Make sure that both parties are emotionally prepared and have enough trust and communication with their partners. Know your wishes and boundaries, and don’t be influenced by external pressure or other people’s expectations.

　　Finally, we should remember that sexual life is a personal choice, and it should be carried out on the basis of voluntariness and mutual respect, and there should be no reluctance. If you have any doubts, questions or need further guidance, don’t hesitate or be embarrassed, but ask parents, doctors, consultants or professional organizations for help.
