Most character sheets actually have a spot where you define the sex of your character. It's a fairly important choice, but what does it mean to you? 

Do you feel there are many differences between male and female characters? Do you tend to favor one sex over the other, or only play one sex? Do you feel a roleplay needs to be balanced with its sexes? Are there certain rolls that you feel are better played by a certain sex?

I tend to play female characters as I find them a lot easier to design and portray. Often it feels like I can play around with emotions and dominance/submissive natures a lot more, compared to any male I create as they seem to be a bland and empty shell or someone that is a stupidly over the top. This could be because I'm a hetro-male and I'm not really branching out and exploring other male personalities, but I dunno. I'm happy playing the pretty lady characters and turning them into Sarah Connor, Ripley or Elizabeth Swann. :sun

As for balance... Nah...
I had fun in one RP that turned out to be a 90% female character line up with one male. We joked and called it his harem, but gender diversion doesn't really make a difference in many roleplays. It's mostly the 1x1s where you're after a certain blend for specific stories. Diversity helps, but it's not needed.
