Both men and women should maintain good hygiene of their external genitalia. It's 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, while women should carefully clean the vestibular region to remove any secretions, helping to prevent bacteria from entering the vagina during sexual activity and reducing the risk of infection. 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 like age, health, occupation, and personal preferences. While general guidelines suggest 2 times per week for those aged 25–35, once per week for 35–50 years old, and 1–2 times per month for those over 50, these are just general recommendations. The most important factor is that both partners feel comfortable and not exhausted the next day. If after sex you experience fatigue, discomfort, or anxiety, it may be a sign that the frequency is too high and should be adjusted accordingly. It's also important to avoid sexual activity when either partner is under the influence of alcohol, emotionally upset, physically tired, or unwell. Mutual care and understanding are essential—forcing or pressuring someone into sex is never appropriate. Ideally, sexual activity should take place before bedtime, as it can help both partners relax and recover energy. For older adults, some may find it more comfortable to sleep first and then engage in sexual activity later. Women should avoid sexual intercourse during their menstrual period. During this time, the pelvic cavity is congested, and the uterine lining is shedding, making the uterine cavity an open wound. Sexual activity at this time increases the risk of 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 avoided in the first trimester (first 3 months) due to the risk of miscarriage caused by uterine contractions. In the third trimester, especially within a month of labor, sexual activity should also be avoided as it may trigger premature labor. Sperm can introduce bacteria into the reproductive tract, increasing the risk of infection. In the second trimester, sexual activity is generally safe but should be gentle and avoid any pressure on the abdomen. Women with a history of miscarriages or preterm births should avoid sex throughout their entire pregnancy. After childbirth, the reproductive organs need 6–8 weeks to recover. During this time, couples should avoid sexual activity to allow the body to heal properly. 3. Postmenopausal women may experience vaginal dryness and thinning due to decreased estrogen levels, which can make intercourse uncomfortable or painful. It’s advisable to reduce the frequency of sexual activity, ideally to 1–2 times per month. Studies show that women who maintain regular, moderate sexual activity after menopause tend to experience less vaginal atrophy compared to those who have no sexual life at all. Therefore, maintaining a balanced sexual life can be beneficial for overall well-being in older adults. 4. Sexual activity should only occur between married partners. Both spouses should avoid extramarital relationships and other risky behaviors to reduce the risk of sexually transmitted diseases (STDs). This is a crucial step in ensuring sexual health and safety.
