It's too late now, but trust me - someday you will not want the internet and everyone on earth to know you paid strippers in BTC - you may not care now, but with the world as it is today - there is a good chance that such things will bite you in the ass in the future. Damage is done, but for the future - it might be something to think about. It might seem like the world is filled with Bros, but it is not - and there lies the danger.
