Unsure about my place in lgbtq

So I have a question.. I don’t really know how to put it..

I have been identifying as straight (I’m about to turn 24 btw)

However, lately I’ve been, curious? Idk how to put it. I was raised in a pretty homophobic household so I think this is why I’m unsure. I fully support lgbtq but wasn’t sure about myself until lately.

I’m attracted to some trans men and a certain trans woman, and started to become attracted towards some women.

My sister is bisexual and she just came out to me last year (she’s 18). I don’t want to feel like I’m hindering her coming out by now starting to come out I guess? Idk I guess I’m sort of confused.

Would I be bisexual? Bicurious? Pan?

Anyone have been in the same place before?
