點解straight 會解做 heterosexual o既？

用straight 來形容性傾向來自同性戀作家 GW Henry 於1941年寫的一本書，他是這樣寫的: 'to go straight is to cease homosexual practices and to indulge - usually to re-indulge - in heterosexuality'.
有go straight一詞在先，今天straight已變成異性戀的代名詞。香港人口中的直是來自英文。
但攣則是港人自創，取其為直的相反詞，外国人並無類似攣意思的字去形容同性戀者。

Yea, you are right. Though not so popular, bent is used in some Eurpoean countries as homosexual.I'll retract my answer soon.

That's not strictly true. ' Bent ' is a slang for homosexuality, a counter-part to ' straight '.

回答者:Au revior！Auf wiedersehen！'s quote from GW Henry is most informative. Thanks!
