[1][2][3][4] In the Western world, generally simple classifications are used to describe sexual orientation (heterosexuals, homosexuals and bisexuals), gender identity (transgender and cisgender), and related minorities (intersex), gathered under the acronyms LGBTQ or LGBTQIA+ (lesbian, gay, bisexual, asexual, transgender/transsexual people, and sometimes intersex people); however, other cultures have other ways of understanding the sex and gender systems.
It may vary over time, too (sexual fluidity), or include attraction not only towards women and men, but to all the spectrum of sexes and genders (pansexual).
[9] In other words, within bisexuality there exists a huge diversity of typologies and preferences that vary from an exclusive heterosexuality to a complete homosexuality (Kinsey scale).
[10] Sexual diversity includes intersex people, those born with a variety of intermediate features between women and men.
In many countries, visibility of sexual diversity is vindicated during Pride Parades.
