Gerda Wegener (1886-1940) was a Danish illustrator and painter who is best known for her erotica which often depicted sex between women. When one looks beyond the explicit sexual content one can see a significant body of work that focuses on other aspects of feminine pleasure - music, dance, fashion, romance, and companionship.
Gerda and her husband Einar Wegener (also an artist) were the subject of a recent motion picture The Danish Girl (2015). Alicia Amanda Vikander, who portrayed Gerda, won the Academy award for Best Supporting Actress.
