I don't have any ideas off the top of my head, but if you want to brainstorm I'm fairly good at playing both genders. I would often play two characters at a time, a female and her brother. I know that doesn't help idea wise...lol. I enjoy fantasy and odd pairings.
And sorry, I'm new, so I have nothing to show for writing skill on here, but I have been writing since I was thirteen. If I'm into the story and once I get into character more (especially hard with new concepts) I get a good flow going.
