Dear Boys (1980)

Lieve Jongens explores the sexual fantasies of a middle-aged writer and the handsome young men who dominate his life. Wolf, a successful writer of romantic novels, is plagued by self doubt and writer's block. Though pleasant looking and well-preserved, he fears age will rob him of the youthful companionship he so desperately craves. With the help of his equally randy and manipulative young sex partner, Wolf plots to seduce the gentle Muskrat from the arms of a much older lover.
