Asexual means your child doesn't feel sexual attraction. Not sexually attracted to either gender, not sexually attracted to a particular person, nada.
Androgyne is someone who identifies as neither male nor female or both male and female. Whereas transgender would be identifying as the opposite gender and cisgender is identifying as the gender you were born with.
So basically your child is saying he or she identifies as both or neither male&female and doesn't feel sexually attracted to anyone.
Im impressed that your child is so self aware and educated on the subject. You should look into it too. Then talk to your child. Be open minded.
