Yes, I think you should start dating. Wait until you are three months into the relationship to tell her about your personal use of unused garbage bags. If you've managed to get 3 months in, it means she is definitely invested in the relationship and you are both still in the honeymoon phase. It's the best time to start discussing outside interests that aren't usually considered the norm.
Heck yeah! Put it all out there! Never know, you might find a female version of yourself! Stranger things have happened....lady Gaga made wearing "meat" a thing!
