This is a good question, because often the authors are figurative with their prompts, not literal.
EG: If an author chooses "learning to dance" but has no actual dancing (or 'sex'- as dancing is often referred to as) in the fic, the figurative meaning could be anything from a journey to know yourself, to know another, to learn a skill such as being social, accepting someone into your life.
If you aren't sure, you can skip the question. Enjoy!
