This is what sparks controversy? This is the least controversial thing I've heard. I'd have been more shocked if people weren't tracking their menstral cycles. There are communities of people deidcated to having sex with horses, keep figures in jars to cum on, get sexually aroused by secretly wearing diapers in public, are trying to spread aids as often and as far as possible, and that unironically watch haz-bin hotel.
And the fact internet nerds want to knock up asians chicks enough to make a website about what day is best to do it is whats causing the most conversation on the internet today?
