I Am Trying to 'figure Out' My Bisexuality

For the longest I thought I was simply looking at other women. Even when I was young when I saw a girl I would think oh she's pretty or I wonder what holding her hands would be like. Yet, I find myself looking at women in the same light I see men more often then not. The same attraction, yet not? For example, I had a crush on one of my male professors back in 2016 and I still think about him to this day. I currently have those same feelings today, but its towards a woman. Now I'm confused as to what my sexuality really is...
