Hey, thanks for playing the game!
Though it's not off the table, for now I don't have plans to add customizations for the MC, sorry.
However, femboy content is indeed planned with different characters (some already in the game, and some that are finished but will show up only in later updates).
Since I will be progressing multiple character routes per update, this will have almost no impact on those who are not into it. The girls are still the main focus of the game, so there won't be an update adding only femboy content, as no update will focus on just one character.
