I have gone thru several such bosy checks, but i think now not
the same.
Pri school: Once, check ur private part and all (They will touch
themselves)
Sec school: Once, private parts also checked. (They will not touch
ur privates, you will do according to their instructions.) Thats
when the female doc ask me to pull more often (dunno what she meant
at that time)
Army: Once, cough and see the jerk, no touch.
