hi

well i agree with that....bcoz today a guy looks first of all for a sexual intercourse with a girl not for love or friendship and this feeling always dominates his feeling as a friend or love interest its not like that he dont like be freind with that girl but the start of any such relationship is SEX...
and the moment a guy gets this he feels saturated and bore with the girl and also develops a feeling that if a girl can sleep with why with not other man.... and that girl immediately becomes witch for her and he starts usisi her like only that way......

all human's create into existence the goodness or badness they define with their brain the happenings they them self experience.
