No matter defecating or urinating, women should wipe their farts from front to back.
The reason is very simple. The defense of urethra, vagina and anus against pathogenic bacteria is ranked as follows:
Urethra < vagina < anus
From the front to the back, you can use the strongest defense force to deal with pathogenic bacteria and reduce the risk of infection.
For men, it is healthier to wipe like this after defecation (yes, even urinating).
However, the male urethra is much longer than the female urethra, which has congenital advantages. It is not a big problem if it is not wiped after urinating.
