[name_m]Hi[/name_m]! Thank you for taking the time and having the open mindset to help me with this. I am female to male (ftm) transgender, which means I was born biologically female at birth but have always felt more masculine and male, and have decided to live as a man. I am planning to medically transition in order to fully look like a man, which will include weekly injections of the male hormone testosterone and eventually the surgical removal of my breasts (top surgery). With these procedures I will slowly start to look like any other man: my muscles will grow, my body will shift to look different, facial hair will grow in, and my voice will get much deeper.
With all that being said, I would like a name that I can use for the rest of my life. I plan on changing my name legally once my friends and family are used to the name I chose, so I want to be sure about it. It doesn’t have to be something that fits the way I look and act now, as long as I grow comfortably into it as the transition progresses. But that being said I know all names have different feelings and “vibes” to them so I also want something that still has a sense of “me” and that fits with my last name. So! Commence the autobiography!
[name_f]My[/name_f] full birth name is [name_f]Kaitlyn[/name_f] [name_f]Bridget[/name_f] O’[name_u]Connor[/name_u]. I’ve been telling everyone new I meet to call me [name_f]Kait[/name_f], for the past few years, since I’ve never really resonated with [name_f]Kaitlyn[/name_f] anyway. I’m turning 20 years old in [name_u]February[/name_u]. I’m 5’5" and have dark brown hair and brown eyes. I have generally pale skin and have a lot of freckles. [name_f]My[/name_f] background is mostly Irish (see birth name lol), but as far as I know theres [name_m]German[/name_m], [name_f]English[/name_f], and Jewish in there too. I’ve grown to be an extrovert and love meeting people and making meaningful connections, but I also need a lot of alone time. I consider myself very empathetic and sensitive to others’ emotions, especially because I’ve lived (and died) through so much with mental illness. I’ve always been really introspective and philosophical. I love all sides of nature but I connect especially with forests and trees, and I love stargazing, space, and the night sky. I also love to have fun and be crazy and let loose! I love people in my life deeply and care about them probably too much.
I technically have been searching for a name for weeks, and a lot of that searching was done on nameberry. But I wanted to see what you experts had to say!! I still feel like I haven’t found the perfect one. Preferences for the name include fitting well with my last name and being masculine or having a predominantly masculine feel. [name_u]Unique[/name_u] names are great but at the same time I really don’t want to be named something super out there, jarring, or noticeably unusual. I guess my perfectly ideal name would be masculine, but on the softer side, maybe with an underlying meaning and/or a reference to nature or astronomy, and sounds like a “regular” or classic name but is less/uncommon at least in the United States. Again my full birth name is [name_f]Kaitlyn[/name_f] [name_f]Bridget[/name_f] O’[name_u]Connor[/name_u]. For reference I was considering [name_m]Matthew[/name_m]/Matt, [name_u]Dean[/name_u], [name_m]Daniel[/name_m], [name_u]Sean[/name_u], etc.
I also am considering a middle name for when I legally change it, so if you have any ideas for that I’d be grateful!
Thank you so much if you’ve read this far! I know it was a bit of a book but it really is important to me and if I’m asking for help I want to make sure you guys have a picture of who I am 
and I know it’s a lot to ask lol but I wanted to venture outside my own opinion of myself because I know I could easily choose a name, then say it out loud to a friend and cringe lol. This means the world to me and I appreciate your help so much!! Thank you!! <3

there is also a reddit group called namenerds that I have seen a lot of trans people on. I wanted to mention it because a lot of them have discussed going through multiple name changes before finding the right fit. It might be a good resource to read up on as you make this important decision 
they had some great tips on trying out a new name! Good luck <3
(I hope you find the right name and have a great new start a being a new you!)
