As well as race, online dating is famous for all kinds of social faux pas. When I was single and dating at least I didn't have to contend with the horror of people fetishising my background, but that didn't stop a breathtaking number of penis pics making their way to my inbox. (A tip: all penises look approximately the same. I know, I've done the hands-on research. A thoughtful online dater sends a pic of their face first.) In fact my time on dating and hookup sites is notable for the fact that only one person ever indicated through his initial contact that he had in fact read to the end of my advert, and dear reader, I married him.
