Hey there! I used to identify as pansexual when I was her age & a little older. What attracted me to the "label" was that I found, at the time, a name for something that I resonated with & spoke true to my feelings, the definition of pansexual being that your attraction has no gender limit. Now, I look back & find it silly. When we're young, we are always searching for our identity & a name for ourselves because it adds to our sense of worth & value, as I got older I just dropped labels completely because I wasnt as concerned with how people perceived me or going the extra mile to express myself in order to stand out. your daughter is obviously very young, impressionable, & curious, & at this age very vulnerable & fragile. so my advice is to respect her identity & let her find out for herself like me. You dont want to put her on the defensive & then her be afraid to share her feelings with you, & even prevent her from exploring further & maybe coming to the same conclusion that I did.
