@maenad simple! take her to a sex toy museum. show her the indisputable evidence. also... do these even exist? they probably should exist.

... my partner informs me that there is one in san francisco... "The Antique Vibrator Museum"... I'm not making this up. They have stuff from the 1800s to the 1970s and stuff. ooo, some of these look kinda familiar. anyway... field trip time!
