My birth middle name I guess is gender neutral, but I always hated it--and to be perfectly honest; my birth name sounded completely trashy and it makes my skin crawl thinking about it.
I went all over the map with middle names. I thought about Tobias (for my dad), Jackson (for my "stepdad"), Jason, Joshua (what my mom would have named me) and Mason (which I kept for at least a year). I ended up going with Jerick as a tribute to someone I look up to; and I've had it since early 2013 I think.
