At another school where a similar class had been arranged, the guidance director stated that the school asked teachers to urge students "in need" --i.e. those who already had friends of the opposite sex--to go to the lecture, "because they would be much more likely to need this knowledge."
而另一所也安排了同樣課程的私立高中輔導主任則表示，學校會請老師推薦「有需要」﹘﹘已有異性朋友﹘﹘的同學來聽，「因為他們派上用場的機會很多」。
