@madloucyr,
I'm going to be crude, but it's to make a point: Do you like pussy? Do you like dick? If the answer to both is "yes", you're bi. It's no big deal. It doesn't mean you have to "split your time equally". I've known women who were heterosexual--no interest at all in pussy. I've known women who were lesbian--no interest at all in dick.
Everything else is just window dressing.
