Open a different browser (one that isn't logged into your account), and see if you can see your question listed in the category where you posted it. There's been an ongoing problem with the spam filter (many months) that causes some questions and answers to only be visible to the user who posted them.
One way to get questions to show up, that has proven effective most of the time, is to move the question to another category, wait a few seconds, then move it back where it belongs. That seems to get it free of the filter and it becomes visible.
If the spam filter is not the problem, here are some other reasons a question might get few or no answers:
*They are posted at low YA user times of day
*They are posted in low activity categories
*They are complex and not many would know the answer
*They don't interest the people who saw them
*They are posted in the wrong category or not the best category to get good answers
