In this paper, I analyze the connections that occurred between the electoral offer of candidate Laura Chinchilla and the new demographic, social and sexual realities of Costa Rica, which help to understand why mainly women and older people voted for her. In addition, I explain the new challenges the Costa Rican society faces in terms of a necessary new social and sexual contract, and the prospect of its approach, or not, by the Government of the first woman President.
