This VN is story first and has been listed as such the whole time, as a slow burn. If you hoped for quick thrills, you didn't read the packaging. If you want porn you can get it plenty of places without trouble. If you want porn in this game, you have to wait until Ocean puts it in. This isn't something that can be argued about. If Ocean doesn't want a dickless wonder like Nika to suddenly jekyll and hyde his way into Ayua's pants until Ocean's ready to render it, that's just the way it's going to be.

If your balls are blue, I'm sure you know how to deal with it.
This isn't about morality, it's simply about common sense. If Nika's mental block was gone, he'd last 2 seconds when flashed even by Marla, and just ruin his underwear. So I'm not in a rush, not for moral reasons, but because it doesn't make sense for a hermit to rip his shirt and go full adonis in the next chapter. It's just not believable, and there's already enough suspension of disbelief.
We'll get there, or stop caring while we wait.
But, knowing that Nika feels up Ayua in a preview render certainly gives me hope that the hermit virgin Nika is growing up
