If you have pain when you go to urinate after intercourse, it is mostly due to the fact that during sex, no attention is paid to hygiene, so that pathogenic bacteria enter the urethra to cause inflammation of the urethra, which leads to pain when urinating. Because the female urethra is short and straight, so it is very easy to attract pathogenic bacteria infection. It is recommended to pay special attention to sexual hygiene, wash the genitals before sex, and after sex, and it is best to urinate once.
