Dear Ann Landers,
When I was fourteen, I made a big mistake with an older boy. Fortunately, I did not get preg-nant. I read in your column recently where you said a girl should not tell her fiance about such things. I hope you will not think I am dumb, but I would like to know if my fiance will know about my mistake even if I don't tell him. I hope you dig what I am talking about.-Sixteen But Not So Sweet

Dear Not So,
I dig, and the answer is probably not. Some-times a girl who has never had sexual relations needs to undergo minor surgery, but this is rare. In most instances there is no 100 percent unmistakable evidence of virginity.
