How did you find out whether you're bisexual or pansexual?

Just asking out of curiosity. For context, I'm bisexual. I call myself bisexual for convenience's sake but I don't really care about labels that much. Personally, I take Robyn Och's definition of bisexuality as my own:

"I call myself bisexual because I acknowledge that I have in myself the potential to be attracted – romantically and/or sexually – to people of more than one sex and/or gender, not necessarily at the same time, not necessarily in the same way, and not necessarily to the same degree."

I like both cis and trans people. Trans and cis have the same genders so I count it as the same. I like non-binaries as well. But I still don't claim to be pansexual. One of the most common definitions of it, other than being attracted to all genders, is that a pansexual person is genderblind. That is, they would include neither gender or sex as determining factors in their romantic or sexual attraction to others.

For me, I use bisexual it is easier to explain and it has a longer history that I can relate to. And I don't believe bisexuality to exclude non-binary people since in this specific case bi can mean "two or more". But I want to know your opinions on it and, if you are either of those or any other sexuality under the bisexual umbrella, which one are you?
