so first to assume i think without is better is not a good start to a counter argument.
Next just because you have a set type you agree with doesn't mean that is the right one. The definition of futanari is Japanese word for hermaphroditism and they have both sexs characteristics. That is another description of it.
Also you have types. Full package, sans pussy, sans dick (for some reason i don't know or understand).
OK then explain the male. If balls are that much an issue for sex with you why in this game the men have balls. Your and the game logic are saying because the balls get in the way they should be gone. And because male monsters exist to there will be a male that gets penetrated. If your argument is "well men not have pussy" ya and catgirls can't get railed by a dick the size of a tree. Your idea is also saying that because im a futa im not being a proper one unless im using my pussy? Ya wife i know you hate the taste of my dick but your teeth are getting in the way of giving me a blowjob. So we have to remove them.
I can respect that. Really i respect the fact your preference is a futa without balls. But you should remember that your not the only human. I'm not fully a futa sure but remember the point where I said "or add a shemale that is the female but has a dick balls but no pussy." Because if you break down fully what I am i am a shemale. I look just like a woman from all the hormones and you wouldn't know i have a dick till I got a boner. And what your telling me here is my balls need to be lopped off and a pussy attached because i don't fit your idea of what you see as a proper futanari or all of my efforts to change what I am should be threw away because unless im willing to mutalate my genitalia I'm not good enough.
