List of books with bisexual or biromantic protagonists. 

Romantic attraction and sexual attraction don't always go hand-in-hand. So while someone who is bisexual may want to have sex with people of both genders, someone who is biromantic may want to develop an intimate, emotional bond with both men and women.
Someone who is biromantic may have romantic feelings towards men and women, regardless of their own sexual and/or gender identity.
