The correct answer to this open question is the following.

Instead of the trite, corny, old-fashion "Once upon a time, in a far, far place...." What about this:
Somebody says this happened in the Middle Ages, but who cares. Not me. The thing is that there are a couple of morals in this story that could make you think about your role in life.
This is a story about character and determination. No beautiful towns, no bords, farm animals in a cozy village next to a beautiful river on a shinny hill. No handsome prince, no attractive princess. Just crude and raw day-to-day issues of life that would make you think how fortunate you are to live in different times...
Someone who enjoys behavior typically associated with dating and love, like cuddling, hugging, gift-giving, love notes, but probably not kissing, etc. and enjoys it with both genders, without necessarily desiring subsequent sexual experience. Biromantic people can be straight, bisexual, homosexual, or asexual.
Jane went out with a girl and bought her this beautiful bracelet. Then they cuddled and watched a movie at her apartment. They don't make out or anything like that. They only desire physical relations with men. They must be biromantic and heterosexual instead of bisexual.
