<modifier name="Eternal Dildo">
Women are expected to wear a dildo inside them. Its shape is flush with the perineum, so it does not obstruct the wearer from sitting, and is not visible through normal panties. With its internal tubing, it doesn't obstruct peeing either. A particular feature of this dildo is its construction from resonant materials that constantly emit weak and silent vibrations. The wearer is constantly kept at a partial arousal state, so squeezing thighs or pressing against it for several seconds can lead to an orgasm. Society doesn't question why women must wear this; they just do. Potentially one purpose is to keep their bodies "ready" for potential action (like when guys want to fuck them) without the hassle of starting dry and needing extended foreplay. Depending on the society, this doesn't mean sex is normalized; in fact removal might imply promiscuity since removal isn't required to pee.
