Personally, I find the ridiculous dick sizes jarring, whether it's a futa character or not. It can be used for fun and work, but often it just looks plain stupid IMO.
I do know that a lot of Futa fans are into those giant schlongs and well, more power to them, I do however also think that for many people that don't mind futa now and then, they are actually put off by it, I know sometimes I feel like that, especially when it's a very slim and petite character without any curves, but rocking a cock that seems half their size.
For me big dicks and big tits are kind of the same, the moment it approaches proportions that seem completely whack, it's more of a turn-off than a turn-on.
As for this specific case, honestly, anyone thinking that reducing the dick size by 20% is somehow kowtowing to pressure should sit down a moment, touch grass and think about it again. NO ONE that objects in any form to the cock size will be satisfied with a 20% reduction. If you want a halfway realistic dick, it's still way too large.
This is clearly something the dev, as a futa fan wants, so I would never put pressure on him to change it, only voice my opinion that I am not a fan of it and why, but they should do what they want, if they feel it is essential to their game.
I will just see how it goes, can I play the game and not be taken aback by the humongous tool the MC swings around, or even have fun with it, or not?
