Thanks for your feedback.
To progress a character's story, you simply have to wait a few days in most cases (which you can do in seconds). This cooldown is intentional and pushes you to follow another character's stories. No grinding is necessary unless you are trying to unlock every outfit for every character as soon as you can. Most income is passive so you can focus on the story.
I'm quite lost as to which fetishes Android has that the other characters don't, aside from optional breast reduction/expansion.
While there is some femboy content, I am not personally interested in it, so it shouldn't be expected.
