Just picture 12 - count ‘em, TWELVE(!!!!!) - rounds of PMS EVERY MONTH, brother... not to mention PRE-PMs, POST-PMS, and all points in between... Brrr....
That alone should clear up ANY fantasy images!!!

Cycles tend to synchronize with women living together, so it wouldn’t be 12 rounds, it would be 1, but with 12 times the intensity.
