Late Bloomer

A middle-aged man and woman meet, fall in love, and decide to marry.  On
their wedding night, they settle into the hotel's bridal suite and the
bride says to her new groom, "Please, be gentle ... I am still a
virgin."

The startled groom says, "But how can that be?  I'm your fourth
husband!"

The bride responds, "Well, you see, it was this way:  My first husband
was a psychiatrist and all he ever wanted to do was talk about it.  My
second husband was an astronomer and all he ever wanted to do was look
at it."  Catching her breath, she then added, "And my third husband was
a stamp collector and all he ever wanted to do was, ... God, I miss
him!"
