"Deceiving others. That is what the world calls a romance," Oscar Wilde once said. And in a romantic relationship, cheating may be the ultimate, albeit predictable, deception. But why do we cheat? British video blogger Emily Hartridge decided to tackle the topic of why (some) men cheat head on.

Hartridge is best known for her series of "10 Reasons Why" videos. She's previously explored "10 Reasons Why Dating Sucks," "10 Reasons Why You Should Get Married" and "10 Reasons We Should Be Allowed To Be Drunk At Work." And -- as with all of her videos -- in her latest installment, she professes some pretty strong opinions about why men cheat.

Her reasons range from humorous -- the timeless "My penis told me to" -- to the more serious -- "He fell out of love with you." Hartridge also discloses that she has had boyfriends cheat on her. "I'm not even going to take the piss out of it, because I have been cheated on and it f**king sucks," she said. Well said, Emily.

Is there anything you would add, or anything she included that you think shouldn't have made the list? Let us know in the comments!
