It also kind affects her story, since her story is intertwined with purity culture.
Her story involves members of martial society shaming her because of her physique, despite her never using it, they nontheless label her as a slut, or as the community here says, a bicycle
The thing is these labels hold power only when there is shame in being sexual, and it is almost 100 percent applied and enoforced on women
If Ai were to become a male this aspect of her story would be diminished, due to the lack of male sexual purity, both in the martial world and the real world.
(Male) Ai would instead be lauded as a player and the amount of (precived) ***(by the martial world and most likely the POMA community) would become a source pride and an avenue for compliments rather than source of shame and ridicule
There is a reason that a man that sleeps around (and is precived negatively) is called a man *****, because all whores are women and being a man ***** is an exception to the rule
Note, there is name for a man who spends time with a women only for their money is called a gilatto (I think), the male equivilant of a gold digger
But that come more as a result of anyone ,no matter the gender, spending time and dating someone purely for their money is almost always precived negatively
