But Marine is a hag and Choco is too. I don't think I have seen Botan talk about anything remotely sexual or even joke about it now you mention it, and at this point it would seem totally out of character if she did.
In defense of Calli she outright stated shes attracted to short guys, so the bi/lesbian stuff is kinda dead with her. Pekora is another non-hag who shuns the yuri/sexual stuff, and Suisei only ever expressed an interest in boys afaik, but she did joke about Aqua being her wife or something but aside from that I don't see yuri-bait.
When I type it all out it seems even weirder that girls still push the yuri stuff given other girls totally avoid sex, are openly heterosexual and they still do fine with their fans. Oh and Towa filtered her fans by having a BF, again she's fine.
Sleeping naked isn't crazy, it's great. I fully recommend it for maximum comfort.
