Also, bisexual/biromantic means to like all genders but have a preference, or to gravitate to one gender more than others, pansexual/panromantic means to like all genders with no preference, you like just because of someone's personality. When you're bi, you can love anyone, but it's possible to only love someone because of their appearance. I felt like clarifying that since you obviously don't know a fucking thing, homophobe.
Being pansexual is that you are attracted to people regardless of their gender, it is the same as being bisexual. In the Bisexual manifesto of 1990 (I think) it is clarified that the term refers to the attraction to your gender and the rest, not to men and women. That is why "pansexuality" makes no sense. Bisexuality stopped being binary for many years.
