Making of a bad bad boy

I have blogged about the 'Brava Bad Boy' books in the past and it has been said not all the heroes are 'bad boys'. How do you as an author define a bad boy? {Erin McCarthy:}To me, a bad boy is an alpha male. He knows what he wants and is determined to get it, by charm or seduction, or in whatever way works. He’s not “bad” as in evil or rude or selfish, but he’s no mama’s boy either. In short novellas like these, I consider the “bad boy” characteristic to play out more in the bedroom than out. These guys like to be in control sexually, pleasing the woman they’re with. Is your Hero a Bad Boy or a Boy Scout?
