Yeah, it's normal. Not everyone talks about it openly, but it's normal and it's allowed. And yes, it's also normal for two chicks to hook up sometimes, just like it's normal for two guys. The majority of people are straight, men interested in women and women interested in men, but there are some people who are gay. Santana has no romantic interest in men, only women. Some guys are like that too. Then there's people like me, I'm interested in individuals, not genders. Guys or girls, either one is fine with me as long as I like the person.
