Blastolagnia is a sexual fetish for young females, usually adolescents. People who have blastolagnia may be aroused by the sight of young women, fantasize about young women, and seek out sexual relationships with these young females.
The term blastolagnia is a combination of the Greek word blastos, meaning a bud, and lagneia, which means lust. That is because blastolagnia refers to a lust aroused by women that can be viewed as “buds” rather than fully-formed flowers.
