 Pennington argues that American Beauty defines its characters through their sexuality . Lester 's attempts to relive his youth are a direct result of his lust for Angela , and the state of his relationship with Carolyn is in part shown through their lack of sexual contact . Also sexually frustrated , Carolyn has an affair that takes her from " cold perfectionist " to a more carefree soul who " [ sings ] happily along with " the music in her car . Jane and Angela constantly reference sex , through Angela 's descriptions of her supposed sexual encounters and the way the girls address each other . Their nude scenes are used to communicate their vulnerability . By the end of the film , Angela 's hold on Jane has weakened until the only power she has over her friend is Lester 's attraction to her . Col. Fitts reacts with disgust to meeting Jim and Jim ; he asks , " How come these faggots always have to rub it in your face ? How can they be so shameless ? " To which Ricky replies , " That 's the thing , Dad — they don 't feel like it 's anything to be ashamed of . " Pennington argues that Col. Fitts ' reaction is not homophobic , but an " anguished self @-@ interrogation " .
