And it wasn't something he tried to do either.  He told me it caused him problems with civie relationships because he could just go on and on and on.......And I couldn't say it was PSE down and dirty action, just non stop GFE for the entire visit.  He told me his girlfriends eventually would ask him "aren't you done yet?"

But this is one man in 8 years I've ever seen like this so yeah it does happen.  
What is the U in USOG for?  Unlimited?  

For the OP, the lady probably thought you would run over your time to try and get another one.  Usually they are harder to reach the more you do.....if that makes sense.  I've had gents overstay because, "I can do it, just 5 more minutes"  Struggling to reach a 3rd or 4th doesnt' seem fun to me.  But if you can do it easily then Ok!
