Lots of gals living together?

A lot of different types of paranormals seem to think it's a great idea to live with lots of gals in one place. What they fail to remember is that women cycle together when they live together long enough. On top of that women tend to cycle at the full moon. So you take a big group of were creatures and you give them the same cycle and you put them together on the full moon. Ouch seems like lots of pain to me. Also seems like broken stuff. Vampires get a bit of luck since most vampires don't cycle anymore. Not so much crankiness to go with life. So just a hint to dudes writing stories with lots of gals in one place. They need to beat up on the guys more often. ;)
