I think a unisex name is actually a good option. It can help when you're in the in-between phase of passing and not passing, or if you're just not presenting one day. It's pressuring to be in a waiting room for example, and not yet pass, but have your name called and it be a particularly feminine or masculine name not fitting your presentation that day.
My birth name was actually unisex and a lot of people ask me why it is I didn't stick with it because it would have been a lot easier. Easier in the sense in the beginning people would see my new name - which is obviously masculine - and assume I was fetching a prescription for someone else. I even had some neighbour redirect my mail, as they were totally incredulous that could be me in the name. It was easier in the beginning before I changed my name, that was for sure. But I wanted a clean break from the old life. I did still want some form of personal connection to a family name though, so I went with the masculine form alternate name I would have had as a child, which I happen to like (luckily).
Definitely pick a name you won't mind hearing hereafter. I'd say go with one you like over one you might be attached to if you want a clean break. Some people want to keep their names as close as possible though. If you like that, go for it. It took a while for me to settle on a name that would work for various reasons, I did think about the implications of a very masculine name compared to my own, but came down in the end to: if I'm going to go through the hassle of changing my name, I want it to be fairly different from what I'm used to, and I might as well go all out. Perhaps I was a bit tired of having a unisex name and felt like the change would be invigorating.
I hadn't thought deeply about the name change before the first GIC appointment... it was only this year I thought about changing it and finally settled on one. It had been stewing about 2 years but I decided during this last year. All the paperwork was done earlier this year. I got the feeling the GIC was waiting on me changing it after I said I would, and I didn't want this potentially delaying my treatment at all, so I got it sorted.
Funniest thing I heard about the new one: "isn't Victor a bad guy/villain's name?"
Well yeah, it often is in movies and books, but it's out of my hands because I'd have been called that anyway if I'd come out right. Blame my grandmother. She picked it.
