I would say pansexual. I've been attracted to men, women, non-binaries ... I'll be honest, I'm attracted to a lot of people of varying genders and orientations.
Also, quinn, you asked "I'll be bisexual (or pansexual; what exactly is the difference?).". The difference is that bisexual people are attracted to only two genders (say, male and female, or agender and female, or genderqueer and androgyne, etc., etc.), whereas someone who is pansexual is attracted to all genders. For instance, I have a friend who is attracted to both men and women, so she identifies as bisexual. I've been attracted to people of every different gender that I've encountered, so I identify as pansexual. There are also people who are trisexual or quadsexual, depending on how many of the various genders they are attracted to. So, someone who is attracted to men, women, and agender individuals would be trisexual, and so on and so forth.
