Could I be bisexual?

So I have always dated/had sex w guys. The thought of sex w men turns me on & my bf is great at making me cum, but ever since I graduated high school I've been having thoughts about experimenting w women. I just never had the opportunity or dont know how to find a girl who'd be down I guess? Still in a happy relationship w a man but I still have these thoughts & I'm always aroused by female-only sex scenes & porn. I've kissed girls before as like a "dare" but was never aroused by that. Am I really bisexual or do I just have bi thoughts bc I'm curious? What do you guys think?
