Both couples should clean themselves before and after sex every time. Taking a warm bath beforehand will increase each other's physical pleasure and is very beneficial to the perfection of sex life.

1. Take a shower before and after sex. Patients with cardiovascular disease may also suffer from myocardial ischemia and angina pectoris. In addition, it is not advisable to take a hot water bath immediately after sex. Because taking a bath will cause blood to flow to the skin and muscle tissue, it is easy to reduce the blood supply to other important organs. Once the blood supply to the heart and brain is reduced, their normal physiological functions will be affected and some diseases will be induced. Sweating after sex in summer will affect your sleep, so you can take a short shower with warm water.

2. However, it is not advisable to take a hot bath for a long time. This is because the blood vessels in the skin will be fully expanded after bathing, and a large amount of blood will flow into the expanded blood vessels in the skin. If you have sex immediately, the sexual organs will become acutely congested, and you must mobilize the distribution. Replenishing the blood in the dilated blood vessels throughout the body can easily lead to an imbalance of blood circulation in the body, reducing the blood supply to other organs, causing dizziness, fatigue, palpitations and other physical discomforts. In severe cases, blood sugar may be low.

3. Daily hygiene of "private parts", wash the vulva and anus area with warm water every day. Use clean water to clean the vulva and avoid using harsh soaps to clean the anus. You need a special towel and a washing basin. Pay attention to washing from front to back. Clean the vulva first, then the anus area. If possible, it is best to use a nozzle to spray.

4. After each bowel movement, wipe the anus from front to back with soft toilet paper. It is best to clean it immediately if possible.

5. Pay attention to cleaning the towels. Change and wash underwear every day. Underwear should be made of soft materials such as pure cotton or silk. Use less chemical fiber and avoid wearing overly tight underwear. Towels and underwear should be dried in the sun. Fungi can easily breed when dried in a humid environment.

6. Whether it is male or female external genitalia, there are wrinkles on the outside of the mucous membrane, which can easily breed bacteria. There is often white smegma hidden between the foreskin and glans of men, which contains many bacteria. If it is not cleaned in time, it will cause balanitis and posthitis. The female urethra, vagina, and anus are close together, and bacteria can easily contaminate each other. Every time you have sex, the man's semen and the woman's vaginal mucus will stick to the external genitalia, and dirt from the vaginal opening or penis will be brought into the vagina, causing inflammation.
