Even though I am legally an adult, I don't feel like one. That may be why I gravitate towards YA only occasionally dipping my toe into New Adult.
Heh...I'm just the opposite. My MF stuff is boring because I always have a romance element even in fantasy but my M/M characters come out to play all the time! I couldn't stop if I tried!I've always been a romantic fanatic and used to write M/F romance but I've been really into MM in the last couple of years and have tried writing stories in that genre--stuff I'm dying to read. Unfortunately those MM stories are torturous to get out even if my brain is teeming with ideas and vivid scenes.
My MF stuff always comes out so easily though. So i'm guessing in my case it's the case of my genre choosing me and it won't let me swap.
I started off writing fanfiction *shock**horror* in my teens. It's what actually started off my love for writing. As most of my fandoms were SF in one way or another, it made sense for me to keep writing it. And I enjoy it. I love SF, cyberpunk, dystopian. It's what want to write.
