Lately I've been thinking I might be bi. I definitely like guys, and I think I might like girls. I don't have any romantic or sexual experience with guys or girls, so I don't really know for sure. How do people who are bi know that they are? And when did you realize it? I'm worried about telling people I'm bi, because what if later on I realize I'm not? I'd feel weird about telling everyone I'm bi, then being like wait nevermind, I'm not. Plus I feel like that would be bad for people who are bi, by encouraging the stereotype that bi people are just confused. I wouldn't want to do that, so I'm not going to tell anyone I'm bi until I know for sure. But how can I be sure?
