The women are freaks in the sheets, but they don't want their husband to know they are freaky like that.
So instead of being a proper married adult and talking to their partner they would rather risk it all by cheating using a organization that make everything on the hush hush with the cheating.
You know what they say? A lot of women cheat on their partner because of the thrill of being chased by a new man only to find out he was only in there for the pussy and not the relationship like her partner.
