Is it rude that I'm not pan sexual?

I'm bisexual, not pansexual. I have nothing against people that aren't cis gendered in a personal matter, but I don't find myself attracted to them. If I was attracted to one and wanted to date them, I'm sure I would, but I don't think that's gonna happen. I've seen transgender people, genderfluid people, etc. that I find attractive but never have I been actually attracted to one. Do you think that it's rude/selfish or something that I'm not attracted to them, or do you think that it's my sexuality and I can date/be attracted to who I want?
