I got an idea recently that I have been very interested to try out with someone of any gender. It's planned out as a long-term but if it isn't interesting it'll be short term.
The idea is this I imagined someone ( you ) living an average human life. You live in a college dorm, apartment, house, whichever you'd prefer. It's open-ended for the most part as for your character. I don't care about gender, age, looks ( for the most part ).
One day you walk into your home and hear a loud thump in your bathroom. You go to see what it was and inside the bathroom you see the shower curtain had fallen. You can see a silhouetted small figure behind it. The figure sputters and moves the curtain from off top of it and before you, you see a beautiful elvish woman. She has light blue skin, silky long white hair, long pointy ears, and a gorgeous young face. It was unlike anything you had ever seen before.
That's where the RP starts. ^_^
I don't have an on's list because it's too long. There are only a few off's and that is scat and vomit. Everything else is fair game.
My character is also not restricted to just an elf. So, if you want to try a different type of creature I'm open to all ideas.
