A list of 1990s American television episodes with LGBT themes includes a number that engendered controversies relating to LGBT representation. With the exception of what would come to be known as "lesbian kiss episodes", in which a straight-identified female character exchanges an intimate kiss with a lesbian or bisexual character, who was generally never seen again, representation of same-sex sexual or affectional displays lagged well behind the behaviour in which mixed-sex pairs engaged. In addition to the controversy that surrounded the sight of two men in bed together on thirtysomething, controversies were generated around lesbian kiss episodes on L.A. Law ("He's a Crowd"), Roseanne ("Don't Ask, Don't Tell") and Picket Fences ("Sugar & Spice"). A similar controversy surrounded Fox's decision to cut a kiss between gay character Matt Fielding (Doug Savant) and a male guest star from an episode of Melrose Place (1994's "'Til Death Do Us Part"). The hesitancy about allowing any expression of same-sex affection on television even extended to the refusal of allowing same-sex couples having weddings or commitment ceremonies on series including Roseanne ("December Bride"), Northern Exposure ("I Feel the Earth Move") and Friends ("The One with the Lesbian Wedding") to kiss at the conclusion of the ceremony. During a period in network television history when producers were pushing the broadcast boundaries on sexually explicit content with such shows as NYPD Blue, the controversy over this and other television episodes that made inroads into presenting same-sex sexuality or affection led producers not to present any sexualization of their gay and lesbian characters.
