I thought "gay" only refers to men, and "lesbian" refers to women, but gay can refer to women too?

That's right! "Gay" can refer to both men and women who are attracted to the same sex. Supposedly the official term for homosexual women is "lesbian," but "gay" is a commonly used term as well. Ex: My friend's sister is gay. Ex: Did you know that Zoe is gay?
