From Goodreads:

Taking the gay novel into totally uncharted terrain, Sacred Lips of the Bronx explores AIDS activism, Jewish folklore, kinky sex, the California New Age, and the streets of the Bronx. The story centers around Mikey and Robert, a young bohemian couple in post-riot Los Angeles whose open marriage is souring. As Mikey's whole world collapses, his past - led by his dead grandmother - rushes in to fill the void of the present. Frieda, as insistent in death as in life, compels him to remember the Bronx of his youth, his first love with a Puerto Rican teenager, and his passion for his ancient culture. These memories force Mikey to reckon with the reality behind AIDS and the millennium-tinged emptiness he feels. By turns funny and elegiac, Sacred Lips of the Bronx is a comic masterpiece set during a time of death and disarray.
