I've been told my name is popular (Adrian), yet I only know one other Adrian and that's my step cousin I've only ever met once, oh and Adrian Brody.
FTM: Alex does seem really popular, ironically that was the first name that went through my mind when I started transition. lol.
Yep, Jake, Jacob, Damian, Dominic, wouldn't say they're bad names just used a lot.
MTF: I can only think of two women that I know of and neither of their names is in any way used often so I'm not going to say. But very feminine names seem to be popular.
It seems from what I've noticed is that a lot of us try to choose something that is either way masculine or way feminine. Which makes sense because we don't want to be associated with a gender we are not.
I like Adrian even though it's neutral (It was originally intended for boys), because I'm flamboyant, I like makeup and nail polish, and I can rock it.

But that's just me.
