This is a great topic, thank you! I've considered amateur night performances myself, but so far have decided against it. Here is my two cents. I think before you decide whether you want to do an audition or amateur night, it is worth thinking carefully about why you want to do it and what you are hoping to get out of it. If your main goal is to show off your pole skills, the audience in a strip club may or may not really appreciate those skills. If your desire is really to perform and show off the results of all your hard work, you might consider seeking out other types of performance opportunities in the pole community, such as competitions or showcases, as the audience at these types of events may be more likely to appreciate the technical and artistic aspects of your performance. And of course you can always post videos on here, YouTube, etc..
As Honolulusushi53412 noted, there can be consequences to public performances. Personally, I have a professional job in a male dominated field, and I do perform, but so far I've stuck to studio showcases and similar events because I feel like those are safer performance spaces for me both professionally and personally. Depending on where you live, your particular professional situation, and how brave you are this may or may not be a concern for you. There are ways to disguise your appearance, and you can go to another city to find a club, but there is always some risk you'll be recognized, and/or photographed.
Also, you may want to consider how you might handle a negative response from your audience. I'm not a small woman by any stretch of the imagination, and while I feel accepted within the pole community, people outside the pole community are sometimes judgmental and even mean about bigger women pole dancing. I do *not* think other people's ignorance should stop you from doing what you want to do, but it can sometimes be useful to think about how you are going to respond to negativity in advance, so that you have a plan for dealing with it if it does occur.
Best of luck to you in your performance journey!
