I am so so so sorry that this took forever to answer, Bicurious is a person that does not know what they are sexually attracted to. They could be attracted to a girl, a boy, or who knows. A stick maybe.
Jo, I don't mind you being demisexual or bicurious at all. My older and twin brother are gay, so I don't mind. I'm not gay or bisexual or demisexual, but I'm not a homophobe.
