I'm a married man, and therefore I have to spend a lot of mental effort making sure that I don't leave evidence of my hobbying activities where my wife can find it, and figure out what I'm doing. That means, for example, having an excuse for being out of the house and out of touch during a date, and always coming home smelling like I did when I left.  

One of the thorniest problems I face is the money trail. I constantly have to figure out a way to accumulate the cash I need for a date without creating suspicious circumstances that will trigger my wife to investigate where the money is going. I'm guessing that this problem is common to married men in the hobby whose wives have full access to the family finances, as mine does.  

One approach I have used is to take $40 or $60 of extra cash every time I go to the supermarket. These transactions show up innocently on the bank statement. If I make a date only once every 3 weeks for so, this will usually work out.  

But I'm interested to know if other guys have the same problem and how they have learned to deal with it.
