What is this thing they call "Date Night"?

My husband is good at a lot of things.  Scheduling and planning date nights are not one of them.  And it drives me crazy.  I am his full time social planner.  The guy comes home from work on Friday to a fully planned and organized weekend that ranges from baseball games to dinner with friends to weekends away. He does not have to lift a finger and his social life awaits.  All I ask is that every now and then, he plans a night out for just the two of us.  You would think I have asked him to do the impossible.  I bring it up for days, weeks, months, and still I see nothing.  Finally I cave and plan something.  And every time I get so annoyed at myself because I should not have bailed him out.  So I am taking a stand now.  The guy needs to be responsible for something.  Maybe I should stop calling it "Date Night" and start calling it "Sex Night". I can almost guarantee "Sex Night" would be planned within an hour.
