I can write either gender. It depends more on the type of RP presented and the current gender balance in characters. As is stands I think I have more male gendered characters just because they needed to be there for the group to balance. Although I feel like I can fit a more adventuring roll with male characters than with the females I write. The ladies I tend to write are either haughty and quick to judgement, or self-sufficient and more reserved (that also happens to be the character types I RP in table-top games, except for my one-armed cleric who had a giant albino bird-mount).
