You didn't say your age -- if you are still young you are just beginning to explore who you are. I really think that sexuality is a multitude of spectrums, not a bunch of false dichotomies. I'm straight but as a young person I had girl crushes while having a boyfriend too. Maybe you are a lesbian, or bi, or a curious and open hearted straight person. Does it matter? Nothing bad can come of just loving others imho.
