I think with the straight/gay labels, you’re not going to be not attracted to someone just because they say that they’re a guy or girl. So really there’s just some appearances that you find attractive, and some not. For most people, those line up pretty well with femininity and masculinity, with maybe a few other restrictions on top. Any label is going to be a simplification, you can’t describe with one word the whole range of people you are attracted to.
