What do you mean, you "want" to be pansexual? And what do you mean by "anyone that a pan person would be attracted to"? Because if you have ever been attracted to anyone you have been attracted to someone a pan person might be attracted to. Pansexual just means gender is not what decides who you're attracted to. You can still be attracted to girls, boys, enbies,... whatever. It's just that something else is what makes them attractive in your eyes.
For example, for me it's important that a person is intelligent and has a similar sense of humor and at least a somewhat similar philosophy in life. Gender is usually a thing I don't even ask about - if it's important to them they'll tell me but I only care as far as using their preferred pronouns if they have any.
