The process of becoming cohabitant has three stages. The first, the “beginning” stage when they become “fiance”. The “occasional” stage was reached when the couple had regular sexual activity and stayed overnight together occasionally. Need for companionship and saving and in some case yielding to women’s demand for the case of males and needs for males’ commitment and sympathy and social pressure for the case of females are basic conditions leading to the last, the “regular” stage. However, in order to maintain their “life style”, the cohabitants have to manage or “neutralize” negative reaction from “social audience” especially their significant others. Various forms of account and concealment were used among males and females cohabitants.
