Gay–when boys likes boys or girls likes girls. Although more commonly used for boys, ‘gay’ applies to girls too. Homosexuality is romantic attraction, sexual attraction or sexual behavior between members of the same sex or gender. The lives of many historical figures, including Socrates, Alexander the Great, Lord Byron, Edward II, Hadrian, Julius Caesar, Michelangelo, Donatello, Leonardo da Vinci, Oscar Wilde, Vita Sackville-West, Alfonsina Storni, Alan Turing and Christopher Marlowe are believed to have included love and sexual relationships with people of their own sex. Terms such as gay or bisexual have often been applied to them; some, such as Michel Foucault, regard this as risking the anachronistic introduction of a contemporary construction of sexuality foreign to their times, though others challenge this.
