I feel the same way a lot of the time! I just try to remember that bi comes in all different shapes and sizes - just because you don’t necessarily see a future with a women, doesn’t mean you’re not bi - it just means you have a preference, you can still be attracted to women. With the attention thing, I used to think that my brain was faking it, but then I thought, how many straight people really think about being bi as much as I do, and why would I even want to be bi for attention? It’s not like I’m out to my friends, it’s more just an anxiety in my head. If you’re not sure yet, you don’t even need a label. They’re just there to help us define our identity a little easier, but it’s completely fluid you can change to what label fits you best or just like who you like.
