I identify as bisexual. I've been married to a man for over a decade, but I am equally attracted to men and women. I would sleep with a man, woman or even both at the same time. If I got divorced I would be open to dating a man or a woman.

How you choose to identify yourself is solely up to you. This is not something that anyone can define for you. I would say if you are attracted to both sexes, you certainly could call yourself bisexual, but if you don't want to that's okay too. There is no right or wrong.
