Essay be damned, but I'll share a list. With some of them I was too young to masturbate but knew they made me feel funny down there. In no particular order:

Barbara Eden, I Dream of Jeannie-ruined many a young boy
Kathy the older daughter in Father Knows Best, Later the Lady druggist on the Andy Griffith Show
Betty Rubble on the Flinstones, loved those well shaped calves and skinny ankles
Mary Ann from Gilligans Island
Christina Applegate, Married with Children
Catherine Bach, Daisy Duke
Meg Ryan in her soap opera days
