Stop whining and enjoy the diabetes-inducing sweetness and fluff. If you're not here for that, just go the fuck away. There won't be much more than that for the foreseeable future, if the anime is anything to go by.
It really is funny how people think they've been together for weeks or months, but it's barely been a week, stated out-right at the start of the Kyoto-Nara trip arc, plus however long that trip took (a few days, at most, probably), and we've been home for less than a day while they sort out their new situation. They haven't even had their first night in the new place. Chill the fuck out.
Like someone else (Glomoro?) said, multiple chapters have frequently taken place during a single day in this manga.
This has nothing to do with virgin or no virgin (I stopped being virgin over a decade ago); this story just isn't that kind of manga. They're a pure, innocent couple gradually getting used to each other, and that's the charm of this work. The fact that Nasa's idea of 'lewd' is basically handholding at the start of this manga should have clued you in. It's been expanding gradually over time. It only recently hit the point of acknowledging that groping might be acceptable soon.
Nasa is constantly realizing new things about what it means to live with a girl or woman, as well. He started out completely clueless. I also feel like Tsukasa has rarely lived with a man before now, likely isolated to the living quarters of the women and girls of Tokiko's family while under their supervision. Even before she met Tokiko, I suspect she kept to herself and often traveled alone. Someone like her, I wouldn't doubt she avoided interpersonal connections for the longest time, until she just couldn't anymore.
