[Air-L] References about profile registration options (gender and sexuality)

Hi all, Could you please recommend me any readings which deal with the design of profile registration options? I mostly look for works on gender and sexuality options in software design (mainly profile registration options on dating sites or internet affinity portals) or any analysis or the interpretation of registration options on the websites designed for sexual and gender minorities. But I will also welcome the recommendation of other works which deal with the issue in a broader sense.
