What is it that a man or women defines as cheating? Most seem to think it's just sexual contact. Well it's not! When you are already in established relationship with someone you can't just go flirting with other people whenever you want. Building a relationship takes time and once the relationship is built you have to keep it interesting. The two main causes of people cheating are lack of interest and un-satisfaction with their partner. The best thing to do is just keep the good times rolling.
