אֵין אַפּוֹטְרוֹפּוֹס לָעֲרָיוֹת

ביטוי (אנגלית)

There is no guardian against unchastity

הגדרה (אנגלית)

It is not possible to appoint a supervisor in matters of sexuality and intimacy. By extension: there is no guarantee or security against the possibility of failing in transgressions related to forbidden sexual relations (originally: even a pious person is not appointed as a guard in a courtyard where there are women).

("They said to him: Most idolaters are promiscuous, he said to them: There is no guardian against unchastity" - Ketubot 13b, and also: "For there is no guardian against unchastity, and whoever is greater than his fellow, his inclination is greater than his, and much youth does, and many bad friends do" - Pele Yoetz, Aleph, Love of the Children)
