I thought I had settled on Lynn myself, but I'm getting some doubts as well now. It's nowhere near what my boy name was though which is good.
My boy name is Yannick (but I've always gone by Nick) and a lot of people have suggested I go with like Nikki or something, but eh @ that.
Also my mom always said that if I had been a girl (and she along with the doctors were convinced I was until the day I was born, fun fact right there) my name would've been Rebecca ... but I honestly just don't like that name lol.
It is quite a hard decision to make though, as it's something that has to stick with you for a long time, so I suggest not doing what I did and really carefully considering all the options. If I do change mine again in the future I'll only do so after having used my new chosen name for a while (for when talking to myself, because I do that a lot) and still being comfortable with it.
