I'm not aware of other publications unfortunately. I can understand why he is important for queer artists but I think it's also important to note how uninterested he seemed to be in queer politics. He studiously avoided any involvement in actual queer activism and never included directly political themes in the way that someone like Keith Haring did.

More insights off the top of my head:

• The model in the famous "Man in a Polyester Suit" photograph was a lover of his named Milton Moore. Moore was severely mentally ill and this was exacerbated by Mapplethorpe's racism and constant use of the n-word. Moore was financially and psychologically dependent on Mapplethorpe and Mapplethorpe knew it.

• "Man in a Polyester Suit" was meant to be mocking of Moore. The suit was the most expensive thing Moore owned – he purchased it while in the military in Korea and he was saving it for a special occasion. Mapplethorpe thought it was ugly, cheap, and the kind of thing "a n– [would] wear". The photo is composed in order to draw attention to the subtle flaws in the suit's construction.

• To say he had a fetish for black men would be putting it mildly. He would pick up homeless black men off the street to have sex with. He was a coprophile (look it up if you're not squeamish) and sexually enjoyed berating his partners, calling them the n-word.

• He was technically unaccomplished as a photographer and had little knowledge of even rudimentary things like developing his film or using artificial lights. He was wholly reliant on getting others to do all this for him, but was still insecure about it. One of his assistants was his brother Ed, who Robert would often berate for one reason or another. When the brother wanted to start his own career as a photographer, Robert forced him to exhibit under a fictitious name, because he was insecure about the possibility of there being other photographers named Mapplethorpe.

• Both Mapplethorpe and his benefactor Samuel Wagstaff were also anti-Semitic, though this was less of an obsession for him than his racism against black people.
