I do have a crossover prize between the two worlds where if you wished to draw the two girls together you're more than welcome to <3. The majority of the characters we have (straight or otherwise) are indeed males, thus picking female characters for this contest was highly difficult. I've put in two females, one in each group, that of which are indeed both my characters to make sure we had girls to work with.
As I've said, if you don't like drawing males there are female options, and if you don't like drawing yaoi or yuri, there are individual options, and if you want to draw hetero, there are hetero options. It's really all based on what prizes you want to go for and what characters you want to draw and have fun with. <3 I've made it so there are prizes for all kinds of different options. 3nodding I know there may not be many options for some of the different combination 'sexuality' wise such as fxf, but at least I was able to include it between the 12 characters we have. @___@
X3 Thanks for asking, and I hope I've answered your question for you. 4laugh whee
