Its only used to replay scenes, you unlock them by spraying her.
I understand that, I've sprayed both characters and I've seen all of their scenes.
I was just unsure if the replay options in the gallery are meant to be permanently unlocked, or if you had to spend a cum token every time you want to replay it in the gallery.
I'm asking since I feel like it not permanently unlocking a scene after spending the cum token makes the new currency redundant, since you get more money for sprays by just playing the game without doing the side thing for the cum tokens. Was wondering if it was intentional or not is all. I like the game though.
