Bro i'm gonna keep it real with you, if you wanna look girly but still want to keep your junk, you may as well play as a futa. However more to the point, the premise states that everyone still thinks you're a guy despite appearances...
Femboys are still a niche kink so don't expect them to add it or other things, like feet or something... I Never personally understood why people can't take H games as is and have to ask for their own personal stuff. It'd be like asking Van Goh to do more pointillism pieces.
