Homosexuality has a lot of media coverage, involving legality of homosexual marriage and the LGBT community. In the dominant stereotypes, homosexual males are portrayed to be very feminine, camp and are shown to be attracted to any other male. They are often shown to be strange or "not normal" and are there as a comedic presence. These stereotypes are supported by some men such as Louis Spence, who is very 'flamboyant'. More recently the media contains more emergent ideology, is no longer portraying them as the previous, and make them seem less unusual. There is less of the dominant stereotypes shown and they are often much more varied in character than previously.
Homosexual females are often shown to be very 'butch' and 'manly', often wearing clothes that are typical or stereotypical to males. They are also often shown as unusual or unnatural, and get a lot of media coverage for similar reasons.
Heterosexual men have multiple stereotypes. One is that they are very sexual or obsessed with sex, and that their only reason for doing things is to 'get laid'. Another might be the opposite of the previous, where he is unpopular and desperate.
Heterosexual women have multiple typical stereotypes. One is that they are 'slutty' and sleep around. This kind of character is typically looked down on and thought to be inferior. Another is the 'naive' kind of stereotype, where she is made out to be naive about her sexuality.
More recently, many emergent ideology is portrayed in the media for different sexuality's. It is becoming increasingly acceptable and normal not to be heterosexual, and it is often frowned upon to bully or harass others for their sexuality.
