My cousin is bi, and my sister has told me she's bicurious, but in a straight long term relationship and doesn't want to give that up in order to explore her sexuality more. Then, there's someone who I'm not related to but we all call her our honorary cousin who was pan, the last time I checked. There's also another cousin I suspect might be gay..?? But that's a theory, with no evidence other than 'there's a lot of siblings there, one must be queer' lmfao. It was really nice growing up with a cousin my age who was also queer. We used to talk about our crushes on girls when we were younger, it gave me a very solid sense of normalcy, even if I was still figuring things out. She was also the first person I told I might be trans when I was 16-17 and she's been an amazing ally.
