According to anatomy, the female vulva has urethral orifice, vaginal orifice and anus, which are very close. Because the female urethra is short and the vulva is in direct contact with the outside, it is easy to be infected. This requires girls to pay attention to the cleanliness and hygiene of these parts at ordinary times, so women should use paper after going to the toilet.
Boys' vulva is long, which is not easy to be infected. Moreover, it can be cleaned by simply shaking after urinating, and it will not pollute underwear, which has health problems.
However, because of the physiological structure of girls, urine can easily flow to vulva and anus, so it can't be treated simply, so paper should be used. And girls will have vaginal discharge, plus the physiological period, it is necessary for girls to use paper. Usually, when wiping with toilet paper, it is wiped from the back rather than from the back to the front, so as to avoid bringing bacteria from the anus to the vaginal opening and causing infection; Girls usually don't hold their urine, drink plenty of water, cranberry juice and yogurt, which can reduce the chance of suffering from urethral inflammation or cystitis; If you have any discomfort or itching, you should seek medical advice as soon as possible! ! And actually, girls don't have to wash their hands and don't touch anything dirty ... There's another joke:
The man asked: Why do women have to bring paper when urinating! ! !
The woman said, "Because men can shake their younger brothers! ! ! Women can't! "
The man said, "that woman can twist her sister!" ！”
Twist your sister ... Twist ... Twist.
Twist your sister! !
