We assume that you find your wife being bisexual to be something very exciting and sexy female partners to your wife to be more interesting than male ones
We assume that if you get the chance to have a threesome with another woman and your wife, and the chance to have sex with that women, it's more interesting than almost anything else
We assume that the more you see your wife naked, the happier, hornier and more frustrated you become. That her nudity is a perk.

We assume all of these things to create a coherent story line. If any of those assumptions are wrong, please understand what we are trying to achieve and adjust to your liking.
Some of the girls do break assumptions, but it is clearly spelled out. Are few are obviously into permanent chastity, so in those paths, it is seen as a good thing: you picked her! In paths where it is imposed, it is seen as a bad thing: you didn't pick that.
