There are three futa characters who may lay eggs, which they can produce. Others are probably just men with tits. In fact, you can create Hiro as a man with tits.
Tits and dressing up seem to make you into a girl in this world. Trudy didn't have them, which probably led to a confusion. Another companion, Kylira, was once called a girl as he looks like one and acts like one.
Unless I'm remembering wrong, there ARE females in this world, we just don't interact with many of them. The Brothel Madame, for instance, doesn't have a penis, and I don't think the nun in the church has one either. Also the angel at the Altar location, but being that she's an angel that's not exactly the same. One of them 2 vampire sisters (the thicker one) is full female as well, with a vagina and everything: in the threesome scene with them you get sandwiched between the 2 of them.
