Homosexuality is sexual attraction to people of your own sex. Attitudes to homosexuality, the decriminalisation of homosexuality, discuss homosexuality.
The word is clinical in tone and now often avoided in favour of gay or lesbian, partly because it was for a century a diagnosis: it was removed from the American psychiatric manual only in 1973 and from the World Health Organization's list in 1990.
