Queer as Folk (1999)

Two gay friends, Vince and Stuart, live on a cocktail of sex, drugs and clubbing. They are both 29, and Stuart is the type of guy who cops off every time he goes out. One night, he spots 15-year-old Nathan, and brings him back to his apartment where they make love. Now, Nathan is still after Stuart, but Stuart just thinks of Nathan as one in a long line of one night stands.
