Both men and women should maintain good hygiene of their external genitalia. It is recommended to wash the vulva with warm water every night. Men should gently retract the foreskin to clean the area underneath, including the coronal sulcus, to remove any buildup of smegma. Women should clean the vestibular region of the vagina, removing any secretions to prevent bacteria from entering the vagina during sexual activity, which can lead to infections. In modern society, it's important to promote a healthy, scientific, and civilized sexual lifestyle. To achieve this, several key points should be considered: 1. The frequency of sexual activity varies among individuals and depends on factors such as age, health, occupation, and personality. While general guidelines suggest 2 times per week for those aged 25–35, once per week for those aged 35–50, and 1–2 times per month for those over 50, these are not rigid rules. The most important factor is that both partners should feel rested and comfortable after sexual activity. If either person experiences fatigue, discomfort, or anxiety the next day, it may indicate that the frequency is too high and should be adjusted accordingly. It’s also important to avoid sexual activity when one or both partners are overly tired, emotionally upset, or under the influence of alcohol. Understanding and patience from the partner are essential in such cases, and forcing or pressuring someone into sex is never advisable. Ideally, sexual activity should take place before bedtime, as it can help the body relax and recover more easily. For older individuals, having sex after waking up and then going back to sleep may be a better option. Women should avoid sexual intercourse during their menstrual period. During this time, the pelvic cavity is congested, and the lining of the uterus is shedding, creating an open wound inside the uterine cavity. Engaging in sexual activity at this time increases the risk of pelvic infections, such as endometritis, salpingitis, and pelvic inflammatory disease, which can lead to long-term health issues and even infertility. 2. During pregnancy, sexual activity should be approached with caution. In the first trimester (the first three months), it is generally advised to avoid sex entirely, as stimulation may trigger contractions and increase the risk of miscarriage. In the third trimester, especially within a month of labor, sexual activity should also be avoided due to the risk of premature labor caused by uterine contractions. Sperm can carry bacteria from the vagina into the pelvic area, increasing the chance of infection. However, in the second trimester, sexual activity may be safe if done gently and without excessive pressure on the abdomen. If a woman has a history of multiple miscarriages or premature births, it is best to avoid sexual activity throughout the entire pregnancy. After childbirth, the reproductive organs need 6 to 8 weeks to heal, so couples should avoid sexual activity during this recovery period. 3. Postmenopausal women may experience vaginal dryness due to decreased estrogen levels, which can make intercourse uncomfortable or even painful. Therefore, it's advisable to reduce the frequency of sexual activity, ideally to once or twice a month. Studies show that women who remain sexually active after menopause tend to experience less vaginal atrophy compared to those who stop completely. Maintaining a moderate and respectful sexual life can be beneficial for overall well-being in older adults. 4. Sexual activity should always occur between legally married partners. Both spouses must avoid extramarital relationships and any abnormal sexual behaviors. This is a crucial step in preventing the spread of sexually transmitted diseases (STDs) and maintaining long-term health and trust in the relationship.
