I admit I don't have much faith in modern horror.
"Vagina dentata" is a male cross-cultural myth seen in numerous cultures around the world (Native American, Greek, African, Egyptian, etc.) in which the man is afraid of inserting his penis into a woman's vagina for fear of his penis being injured by the supposed toothed vagina.
"Toothed vagina," the classic symbol of men's fear of sex, expressing the unconscious belief that a woman may eat or castrate her partner during intercourse. Frued said, "Probably no male human being is spared the terrifying shock of threatened castration at the sight of female genitals." But he had the reason wrong. The real reason for this "terrifying shock" is a mouth-symbolism, now recognized universally in myth and fantasy: "It is well-known in psychiatry that both males and females fantasize as a mouth the female's entranceway to the vagina."
Cakes are not the only culinary items adorning the vagina these days; click here for an earlier post with a recipe for Vagina Muff-ins.
Even if you are not a baker, at least click to see what a muff-in looks like!
