Yeah, that would unlikely unless she was being controlled. Since Usagi doesn't seem to show any interest in anyone other then Tuxedo Mask and their daughter. 

Harem, possible though

I may eventually reinstate an old roleplay idea where the y chromosome has been severely deteriorating so that men are born less and less until they're near extinct, thus making the entire human race threatened by extinction by the time there aren't enough men around to get women pregnant. This would obviously lead to some yuri action (there aren't enough men around to keep everyone satisfied). Once this roleplay ends, if you guys like the idea then we can have another roleplay involving this. However, I probably wouldn't have it take place in a school so we can have a change of scenery. There are many more story ideas that go along with this plot then have it simply be a romance anyways. After all, if nothing drastic is done then entire countries can fall, so it ignites plenty of wars.

So it's kinda like that manga called Blue(I think)? Cool cool xD
