There is nothing wrong but unusual .Younger the wife is merrier.  

Nope.  I'm 5 yrs older then my husband and we have no issues.

Why would anything about the situation be wrong? You're both consenting adults.

Your age jumps around with your sexuality, marital status, and parenthood (and has for years). Yes, it's wrong for you to repeatedly post fake stories on YA (and then complain when called out on it). 

Society makes it look wrong, but as long as you love her then everything is right.

No.  You are both adults.  Five years is not a big deal. 

By my math she's either four years older or is actually 28. But the only thing wrong with this picture is that you're about two years too young to actually make a lifelong commitment. There's a reason people who marry at your age have an 88% divorce rate.

No I definitely think you really did just turn 23.  And, wait a moment,   yes,I can see it now.  Ah your wife is in fact 27 so you didn't get it wrong at all.  Those are definitely your ages.  Was there any other question that you wished to ask?

You don’t have a wife, Sherlock.  So it doesn’t really matter.

It does not matter to anybody but you.  If you think its wrong then why did you marry her?
