Juliette (Marquis de Sade)
Male and anonymous authors continue to focus on lesbians in male-gaze pornography and crude sexual satire. The female authors in this group are instead writing of their own lives, whether the continuing poems on the theme of intensely romantic friendship, or the somewhat banal diaries of the most famous female romantic couple of the age, or the somewhat more transgressive (and likely sensationalized) memoirs of the cross-dressing/genderqueer Charlotte Charke.
Literary women who love women often lament being "the only one" or consider themselves outside of nature, but in the 18th century this begins being transformed into a sense of monstrousness. Versions of Ovid's myth of Sappho's late-life conversion to heterosexuality begin to presage this shift in the early modern era. Though a straightforward reading of Ovid's tragic ending would be that heterosexuality was the death of her, it began to be framed as a retroactive punishment for her previous love for women.
