I prefer female PCs, since I really like all kind of F/F scenes. And with a female PC I can still have F/M oder M/F scenes, when I'm in the mood.
But as you can see, opinions are quite different. So giving people a choice might be important, if you want more people to play the game, even if it means more work.
But like Kuidelu already said, you'll never please everybody. You can only try to please as many as possible.
