You can set male enemies to be femboy's, which I think increases their butt size? Never used it myself, but I know the option is there in the options menu. And for the player character, you can customize it out the wazoo, and make whatever you want.No femboys/traps?
Also, I know some people have complained that the male enemies look rather feminine. Again, I wouldn't really know, because I went all female, but it's entirely possible it will be right up your ally.
You can also make female enemies futa, or a female character futa and just shrink the breasts if you want a femboy that way.
There is lots of customization in this game.
