Lee suggests this book as a possibility --

The chapter I was thinking of earlier about race and online relationships (not exactly dating) is titled "Fucking with Fucking Online: Advocating for Indiscriminate Promiscuity" by Michael J. Faris and ML Sugie, in Why are Faggots so Afraid of Faggots: Flaming Challenges to Masculinity, Objectification, and the Desire to Conform (Matilda Bernstein Sycamore, ed). Its only 7 pages or so long. A lot of the other chapters might work well as optional reading, as well. I really liked another chapter called "Trans/Nationally Femme: Notes on Neoliberal Economic Regimes, Security States, and my Life as a Brown Immigrant Fag" by Debanuj DasGupta. Other chapters might be hit or miss.
