Yeah, that bitch is insanely annoying (and definitely looking to become his newest stalker), but this whole thing about not being able to fuck until the hole gets repaired is an entirely made-up problem. They can go to a love hotel any time they goddamn please and fuck like rabbits all night long, but as is typical for this manga, everyone becomes completely retarded when the plot (i. e. the author's obsession with protecting the MC's virginity because apparently they think that's comedy) demands it.
