Bisexual???? in I Don't Honestly Know

Am I bisexual is something I have been thinking about a lot lately, and honestly I don’t know how to answer that question myself. I have found myself attracted to woman before however I have never actually had a crush on one, I’ve also found myself looking or wondering a little more than I think I should have when it comes to seeing a woman in public or even seeing a lesbian couple online or in real life. I have also thought about woman in more of a sexual relationship rather than just a significant other. The thing though is that I am definitely still half straight because I am still attracted to the male gender and have indeed had crushes on males before. So am I bisexual or am I just bi curious?
