If a woman finds a man (or another woman) that can give her either emotional or sexual satisfaction, she may cheat on her spouse or committed partner for the pleasure of an intimate connection, even at the risk of losing what she has at home.

Humans have a natural proclivity to move toward what feels good.

Some even describe it as "swinging from one branch to another" to make sure that they have prospects available before deciding to make the change.

There are three common experiences for women who have had affairs, and although these are not excuses for cheating, they may explain why some women step out and others stay home.
