According to Osho, what happens when women give up sex is irrelevant to you; your concern exposes your own repressed sexuality. There is no external thermometer for transcendence - only personal truth. Stop judging others and turn the inquiry inward. Projection makes everything look sexual; awareness dissolves it. Respect others' freedom, watch your own mind, and transcendence unfolds naturally, not by outside scrutiny.
Don't worry about other people's sex; if it bothers you, it's your own feelings to look at.
