She lost her virginity to her ex-fiancé Levi Johnston on a camping trip after getting drunk for the first time on too many wine coolers. Palin made the revelation in her memoir entitled “Not Afraid of Life: My Journey So Far”. The single mother and daughter of former Alaska Republican Governor Sarah Palin writes that she had vowed to wait until marriage to have sex but awoke in her tent alone with memories of what had happened as Johnston talked with his friends on the other side of the canvas. Palin’s memoir, co-written with Nancy French is scheduled for publication next week and covers not just her lost virginity but growing up with her family and the excitement of her mother’s political life.
