You don't need to check your anus for the college entrance examination. But you need to check the external genitalia. The process is that the doctor walks up to you and asks you to pull down your underwear (to your knees or ankles), then open the foreskin and palpate your testicles and penis. This is essential for the college entrance examination. In some areas, in order to shorten the examination time, students will be required to take off their clothes, shoes and socks for surgical examination, so this is also the reason why students are worried about anal examination. Hope to adopt, thank you! !
