Idk what to think

So i dont really know if i like girls or im bi or just overthinking everything. A few years ago there was this girl at school that started dating other girl, and she said that me and my best friend will end up being girlfriends too and that, and we did tryed to kiss and all, and i actually liked it, but never really told her or anyone. And i actually started thinking i might feel atracted to girls. Ive never had a boyfriend but i did had a few crushes and all. And this year a few months ago, i was at this party (im in college now) and ended up doing it whith a friend of mine, and i did liked it.(shes bi btw). So the thing is in just want to know an opinion if im just getting draged by the emotion or if i really like girls. (im sorry for my english, i actually speak spanish).
