Tbh, the knowledge that even lesbian sex could lead to nasty parasite infestations, only possible to het intercourse otherwise, would only horrify me; no idea how they could be thrilled about it, or even going at it like rabbits after knowing that. And they are only schoolgirls too. I suspect it's a thing with male authors, and this author in particular, what with all those balloon boobs and hentai angles. Anyway, there's just something really disgusting about the way most of these male authors see and think about women, and I don't like it.
