well, I think the ideal thing would be to use the feminine form of your name, my name was "Alfonso", that name is as masculine as masculine can be here in Mexico, the feminine counterpart was "Alfonsina", it's horrible, I seriously hate it, so I went to the internet, checked lists of girl names and decided my new name would sound at least a little like my old one, now, my dad gave me that name and I feel bad about changing it, but I can't live with that name anymore, so after a lot of name searching I ended up choosing "Alanna", it means Brilliant or shiny I don't know, either way I liked how it sounds with my middle and last names, so Alanna I became.
