These numbers are for the Yume game, I haven't counted Smashboy or the other games because I already know that the sex to foreplay ratio is very bad there, especially in Smashboy.Oh you counted! 31 foreplay to 14 sex is higher than I thought! I think Smashboy must've been less though.
Might work for people who are both masochistic and imagining themselves to be in that situation. I am neither so foreplay only or denying anything does much less for me than actual sex. I wanna see someone, male or female, having a seriously crappy day on the receiving side of a rough sex scene and the character who inflicts the sex having a blast because of it. Thats pretty much what I play these rape genre games for in between other games. Gameplay, story and an unique artstyle are of course nice additions as well, which was probably what saved the first Excessm games from turning me away from the developer completely because they surely did not have too much in terms of lewd content that I really enjoyed.I think it has to do with the whole femdom fantasy, and sadomasochism themes, where the guy is not worth the sex so he gets whatever the fuck it is the female is willing to give him. Sex being the biggest and most unlikely prize.
In any case I consider the increasing number of actual sex attacks/scenes in Yume to be a good thing, as it came together with an increase of total scenes to boot so there is still plenty of foreplay for the people who were only into that. The game even had game over scenes with dialogue for all the enemies, something I really missed in Smashboy too.
