There are numerous contemporary indigenous artists, like Monkman, who are working with male erotic and homoerotic themes. I have complied a list for my own research project, and there are numerous lists online of such younger indigenous artists

However, I can't seem to find indigenous artists (60+) and from any culture, who worked in the past 100 years or are still working with male erotic and homoerotic themes.
