Dorian Gray

The Picture of Dorian Gray was a novel written by Oscar Wilde and first published in July 1890, in Lippincott's monthly magazine. 

The magazine's editor feared the story was indecent, and without Wilde's knowledge, deleted roughly five hundred words before publication. Despite that censorship, The Picture of Dorian Gray offended the moral sensibilities of British book reviewers, some of whom said that Oscar Wilde merited prosecution for violating the laws guarding the public morality. In response, Wilde aggressively defended his novel and art in correspondence with the British press, although he personally made excisions of some of the most controversial material when revising and lengthening the story for book publication the following year.

I don't remember any gay content in the old films that have been made ,  so there may  have been more censorship at the time.
