Virginity

Virginity was the state of a person who has never had sexual intercourse, a virgin being the term for an individual who retained their virginity. Several spells required the ritual killings of human virgins, and many demons fed on or accepted virgins as offerings (particularly females), due to their perceived purity.

Kleptes-Virgo, meaning virgin-thief, referred to a group of different mythical creatures from various ancient cultures that preyed on male virgins by assuming the form of their female counterparts and seducing them.
