I think they can make the game so both sides are happy, if you want slow burn then just pick those choices so she she goes at your speed, and if I want her to be a turbo slut, I should be able to pick those choices also.
The problem that most games have is there is a corruption meter that they have to be at to get sex scenes and you might not have enough cause you turned down a old smelly hobo, so now you have to go back and blow him to get the points.
Fuck that she should be able to be a selective slut like Myriam, she gets to pick and choose who she fucks or fucks them all.
As long as this game gives you choices to keep going or to wait with some character without it closing there path completely it will be successful game.
