No, please NO.
If that is the content you want, there are plenty of games that have it. Go and buy/support/play those titles.
A large majority do not want to see futa/trans/gay content at all. Please do not ask for it in titles that appeal to the mainstream. Most of us will lose interest in any title that adds this type of content.
I am not saying that your interests are not valid... I am saying go and find your kinks in titles that already support them.
If I were to go into the comments of futa/trans/gay titles and ask them to add more straight content I would be ridiculed, down-voted, and ignored. What makes you think that doing the reverse would give you a better outcome?
