Girls should pay more attention to the hair in the private parts, not the inside of the vagina. Hair in private parts is easy to adhere to sweat and excrement, which leads to the growth of bacteria and becomes a source of odor. People with pubic hair may need a little treatment to reassure themselves. Of course, if you like the prosperous scene, you can leave it alone.
On the contrary, if boys have foreskin, they are more likely to shelter evil people and breed bacteria, and need to be cleaned well, otherwise it will increase the risk of female vaginal infection or infection. Because men can wash the bacteria off Tintin, but girls are not so easy to clean their vaginas, so girls are at higher risk of getting sick.
