rape in childhood ties together sex and affection in an unbreakable bond. if they won't have sex with you, or do sex to you, then they will not stay, because the one who stays is the one who does sex to you. you must let them do sex to you if you want them to stay. this is obviously then reinforced by entering sexually exploitative relationships with people and the internet as you grow up.

this is what is commonly known as "borderline personality disorder".
