First, the vulva
The pubic hair and pubic hair protect the vagina like eyebrows and eyelashes protect the eyes. So shaggy pubic hair habits and customs are not good.
Four sizes of labia are closed together, but the vaginal wall is tightly placed before and after, double insurance. Unbreaked hymen also has some protective effects. When standing and sitting, the vagina is high inside and outside, and it will not be filled with water or water. British scientists have done scientific experiments with litmus reagents: Even pregnant women do not have vaginal water in their baths.
Second, the vagina
Although the epidermis of the vagina looks pink, it is not the same as the inner skin of guts such as the intestines. The inner skin of the intestine is composed of a single layer of cells, while the vaginal epidermis is composed of many layers of cells, and the surface layers are ageing and hardening, like the heel of the heel hardened is a reason (of course less than the foot), anyway, is to solid. The epidermal cells are constantly falling off, making it difficult for microorganisms to take root and settle home.
The vagina is usually acidic, with a pH of about 5, and it can reach 4 during pregnancy. Acidity has an inhibitory effect on most harmful microorganisms. If you often use water to wash away these beneficial lactic acids, then unfortunately. Blood, semen, cervical mucus, gray manganese oxide, etc. are alkaline substances that neutralize and destroy the acidic environment.
Good bacteria in the vagina also inhibit the propagation of harmful bacteria and maintain a normal ecological balance. Do not use drugs to artificially destroy this balance and remove the tiger from the mountain. Monkeys will be called kings.
