Am I bisexual or am I lesbian?

It all depends on what your feelings towards men are. You can try to picture yourself with men, both in sexual and romantic contexts, and try to analyze how you respond to such ideas, what your emotions are when you fantasize about it. If you feel attracted towards men, if you respond with enthusiasm and desire to those scenarios and you have the same response when you picture yourself with women, then you are bisexual. If you find women attractive, but you don't feel the same about men, that would make you a lesbian.

The only person that can answer this question is you! Labels can be finicky because for some, they're something concrete to hold onto, and for others, it can be something restricting. There is absolutely no need to rush through figuring your sexuality out-- this will come to you with time and as you meet more people. Speaking from my own experience, it took me a long time to figure out my own sexuality. I fluctuated between probably 3-4 different labels, all within a few years time span. And none of them felt right, either-- not until I found a label that best fit me and just felt intrinsically right. I really wish you well in your journey of self discovery!
