s it possible to have 2 sexualities?

hello everyone,
So I've been questioning this mainly because I have a friend who says that they are Bisexual and Pansexual.. I thought you can only have 1 sexuality, so it's been bothering me for a while.
Even tho I'm part of the lgbtq+ I still have a lot to learn about other sexualities. And this one is confusing me, if they don't care about the gender and only focuses on personality doesn't that just means she's pansexual and not Bi?
