Maybe you should better watch porn instead of playing visual novels
?
There you will find everything you named - no need to be a love interest, no boring male plot lines + no story and even a whore in a main role that is fucked by herd of strangers. It will be like your dream become reality, because if you add everything you wrote to an adult visual novel, then most likely this game will be doomed to failure and devs will go bankrupt even before they get their first paying subscriber
Thats why!
No offense.
