Whats your reason to cheat? Lets keep aside morality and get down to brass tacks!

It could be anything from Adventure, thrill of doing something secretly, gaining self confidence (extra love?), libido mismatch with existing partner, temporary cold war among couples, finding opportunity with that hot person whom you can have but cant own..cheating has existed since relationships came into being and is seen with different lens for different genders, religion and cultures. Mankind has experimented with all social models from legalizing paid sex, polygamy, having concubines....urge to mate with more partners may also have to do with theory of evolution and biological nature. One must remember the world of relationships is never black & white but shades of grey! http://fusion.net/story/151773/women-sex-partners-dating-study/
