I think 18 is the minimum age... and you can keep it hidden by only taking public transport and not wearing the clothing or make up that reflects that you're a stripper anywhere other than the club. However, I would suggest that you don't take this job, because this is one of the worst jobs I can think of, you get paid for arousing people and there is no dignity of yourself. If you haven't stepped into this pile of bullshit yet, please take my honest opinion and don't step into it at all. But if you still wish to do it, do it. But this in your mind that if you have even a little bit of dignity and self-respect, you will regret it. I hope you take the right decision, good luck!
