Yeah that is... not very unisex. I would do something like
Arin or Aryn that isn't as traditionally feminine. Arynn is maybe the most appealing spelling. Also, Mad is already kind of unisex, because of
Maddox. I might pick
Max if I were them. I would say
Erin is actually more feminine than Mad...
I like to imagine NB names for myself. I kind of favor
Rio today. Or maybe
Avi.
Avi is so nice.

NOTE TO SELF: Names I like:
