Many new writers are wary of asking questions because they don't want to appear unprofessional.
Experienced writers, on the other hand, ask as many questions as they can. They ask because they don't want to misunderstand the parameters of a project. They cheerfully nag their clients for information. Indeed, if the client doesn't respond quickly to requests for information, a professional writer will often refuse to take on the project.
If you're shy of asking questions, don't be.
Asking questions has often developed into fun projects, and wonderful relationships. :-)
