I do believe it is a personal thing, some women will hate having a boys name, some women will love it. I'm mostly annoyed because perfectly nice boys names are becoming girls names. So people who want to use a great boy name has to worry about their son being made fun of for having a "feminine" name.
For example, Rowan and Rhys. I love both of these names, but now they are being used for girls and it deters me from wanting to use them on a future boy because I don't want him to be made fun of.
I would also worry about my daughter, if she grew up to be a tomboy or whatever, I wouldn't want to give kids something else to use as ammunition to make fun of her.
I mean, there are SO many beautiful, cute, spunky girls names, whatever your style. I don't see why anyone would have to use a boy name to be unique or different.
