Asuka is neither a woman nor a man, they're X-gender (a non-binary identity) and they've realized they like women! Okay, now what?
 
Adult films are fun to watch, but real sex is less appealing. Would having a penis make that better or worse? Periods already suck, and sex means more fluids from more people! This autobiographical manga follows Asuka's feelings about their body, their relationships, and the fun (and sometimes terrible) experience of having an awakening in their thirties.
