This the kind of story I could always visualize Joan Rivers telling but this really happened to me.
My mother had never explained anything about sex to me and when I was twelve years old I had to go into the hospital to have my tonsils removed. While under anesthetic my period started and when I came to, I was a bloodly mess.
I thought that either the doctor didn't know where my tonsils were located - or
obviously, I didn't.
To this day I still have more than the usual, terrible fear of surgery.
