Quoting MissteriousOne:

In my opinion, being a Cougar is neither learned, nor won due to age and experience. Being a Cougar is a lifestyle. It's an attitude. It's the way you choose to be... the only way you can be. It's knowing what you want and enjoy in life... especially younger men and everything they are, or could be with you beside them. It's going after what you want... making the first move if need be and having no need to apologize for doing so. It's possessing inner serenity, confidence and complete self-assurance when you walk into a room. It's being non-judgmental. It's not wanting to be fenced in and not wanting to fence him in. It's finding younger men exciting, stimulating in every possible way... and finding your peers and/or older men boring in all ways. It's the younger man choosing to be with you because you are intelligent, sexy, secure in your own skin, open-minded... non-threatening. You welcome anything into your life that fulfills your needs as a woman... accepting and receiving pleasure as you wish, as you choose. And, it's having the power and carnal knowledge to do so. It's the attitude that you are worth any and every effort and deserve all you desire, anything you want. The younger man, the Cub who prefers a Cougar... wants a woman with all these attributes. He knows all those things about you instantly and he gravitates towards all that you are... because you are who you are, because you know all there is to know about most things he cares about. You know how to entice him, enthrall him, enjoy him... please him. You know you are a Cougar... and, are totally and completely proud of it.
