if they make an ongoing thing of sleeping with many different men, then that there is a big, big problem
true.. if a woman/man is unable to find happiness on one man/woman, she/he can not find happiness at millions of women/men. it is like that everybody has eyes. when your partner has a dust particle in her/his eyes and if you dont understand this, you may look for others who see better... this means you are selfish in sex and you can never be happy and can never make any happy if you are selfish.
