Yeah, there's also that. Having a dick, breasts, asshole, and vagina gives more options for them to fuck/get fucked. Removing the vagina just lowers those options.Funny my origin story with futa started because my horny ass kid wanted more pleasure, breasts, anal, vagina weren't enough I wanted more so at that time futa was my answer. You got both dick and vagina oh shit that's fucking hot you can fuck both of em and still keep the breasts and vagina part, you just got an extra muscle to add to that pleasure stimuli.
I feel like it's such a waste to have a woman character and not add a vagina, you can essentially get fucked and be the fuckening. Two worlds in one body.
