Boy you are sicko.

It would be difficult to get as I will have to work extremely hard to get a girl to take her pants off.
Anyway I wonder about the fs saunas in China where the girls probaly live together in a dormitory on the premises. When one is on the rag, there is a high chance her fellow wgs will be on the rag at the same time.
This is based on a study discovered when females live together, their bodies would 'sync' together in hormonal sense and have their periods together at the same time after living together for a few months.
Or does management of these fs saunas put all the girls on the pill?
