That's odd, because I feel like more often than not, Arisa is the one initiating requests for some sort of intimacy. She's always really eager to do something, but then freaks out when it comes right down to it because she's unsure of what to do, or just gets too excited and loses her cool. When she thinks about the "old" Arisa, she gets really jealous of "her" and her ability to be so forward with Mari.
There are also times when Mari tries to initiate, and a lot of those times Arisa gets flustered. Much of that seems to stem from the same lack of knowledge on what to do with more intimate advances. (Or, occasionally, being overwhelmed by how cute her girlfriend is.)
There's plenty of other jokes too, but seeing as the manga is about their relationship, it would make sense that gags revolving around their desires for each other would be a recurring theme.

The first six pages of Ch. 14 are very much about their desires for physical intimacy (and Mari's lack of agency prior to that point). Both Mari and Arisa are clear that they want to have sex, with Mari explicitly saying so on the first page. On the next page, Arisa is shown worrying about her current lack of experience, but after that she expresses her remorse over having been so timid up until then, and states that she, too, wants to have sex.
Of course, this is followed by Mari killing the mood somewhat, but I also think she's stopping there because she wants to let Arisa fully prepare for this thing they both want. She doesn't want Arisa to feel uncomfortable for their "first" time together. This whole sequence ends the next day, with Mari saying that she will let Arisa take things slow, so she can remember what to do. Mari then concludes with a bit of narration that expresses her sincere love for Arisa, no matter what. Whether Arisa is still the same woman she knew, or has become a different person, Mari loves her.
