Fourth Time Lucky!

A middle-aged man and woman meet, fall in love, and decide to get married. On their wedding night they settle into the bridal suite at their hotel and the bride says to her new groom, "Please promise to be gentle,... I am still a virgin."
The startled groom says "How can that be? You've been married 3 times before."
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 a gynecologist and all he ever wanted to do was look at it."
"And my third husband was a stamp collector and all he ever wanted to do was... God I miss him!"
