Watching porn is a substitute
To derive sexual pleasure from.
Visual stimuli are at work.
Taboos in sex boost seeing porn.
Straight man and woman access porn
That features heterosexual acts.
Gays and lesbians access porn
That pictures homosexual acts.
Bisexual man and woman watch
Porn of both types with interest.
Men other than gays access porn
Picturing sex between two women,
Where there are two stimuli at work
To feast men's always starving eyes.
Banning possessing porn materials
Is an assault on sexual freedom.
