Just in general yes, there has been a sex scene in the game for a while.
The MC hasn't had any penetrative sex yet(have to say that since some people don't consider oral sex for sex).
Well to put things in perspective. If me and my wife does not have sex in more the 2 weeks (16 days) especially if either of us is extremely horny during that time, something seriously would be wrong, that is not normal IMO. Being coy only works for a couple of days, then you straight out ask "Honey, I was so frigging horny last night, why did you come to bed so late? come to bed earlier so the we can have some sex."
I do not understand going 2 weeks without having sex while being sexually frustrated. Even if you're tired, you just fucking spoon and put it in. No effort and viola, both feel some release.
I think this frustrates me the most in this game. I initially played as a good wife with some light flirtation in between, but damn. With such a bum of a husband, her "Filthy" rout is not filthy at all. She's a prude on the filthy route!? What frustrates me, is that you have the premise of a marriage, there is no reason to keep the audience without sex scenes while the husband is around.
What normal wife would still not walk around horny with her husband not paying any attention to her? The Good wife route for me is totally unrealistic. The hornier you get, the more everything that moves make you horny. I mean seriously, after the mishap with the sexy clothes, he just returns to ignoring her straight out?
The way that Our Fate does it is more realistic. You bang your girlfriend while starting to develop feelings for someone else.
Once you feel that your feelings for the new girl is too much you cheat or break it up. etc. etc.
Sorry about rambling.
TLDR: The premise of a marriage makes it unnecessary to blue ball the player to this extreme. One sex scene somewhere in the game could have given player a sex scene without changing the overall dynamic of the game. The premise of the game is an adult game after all? This frustrates a lot of people playing the game.
