I think Cougars rock, but i only know of the animal
Cougar - Wikipedia, the free encyclopedia
As for being labelled by others theres quite a few names that GLBT are saddled with, but not only labels but also preconceived assumptions about our lifestyle, our choices in fashion, culture and depending where you live an assortment of legal prejudices that inhibit our rights to live the same way as our heterosexual brothers and sisters. yes its bullshit.
As for the cougar comment i think you need to say "f**k em all!!!" you are your own person and once your self esteem is strong in the wonder of your own self (as wonderful as all others) you wont need to be bothered with the comments and labels of small minded bigots and hating charlatans.
also as long as you're both consenting adults its noone elses business.
