Do you think I'm biual? Is it bad?

I think I'm kinda . I'm a 17 year old going on 18. I'm a guy. And ever since I've watched that movie Terminator Salvation with that guy (Sam Worthington). I felt like in loved with him like when you see someone for the first time and you know that's the one for you. Well like my stomach felt like sparks of erflies. Since then I can't stop thinking about him. I still like females. I mean like hmmm there so yummy. I honestly don't knw what to choose for the future. Plus, Sam caused this man crush I have on him. Is it bad feeling this way. I have a phyciatrist but I honestly feel shy talking about that.
