I'm confused

Ally
I need help! I don't know what sexuality I am. I think I might be bi. My first kiss was with a girl, and when I was first introduced to porn, I only watched lesbian... it was just what turned me on the most. I have had boyfriends in the past, but I don't know if it means anything that I think it would be more fun to date girls. Also, to top things off, I'm finding myself checking out heaps of girls and following 'hot' girls on social media. I don't know what to do, and I don't know how to sexually identify myself.
