I have an impression that Brokies tend to be heterosexual women or gay men, and I would like to test it. All self-selecting polls are statistically valueless, so the results of this can only be expressed as "Of those who answered, x said they were..." So far as I know, there is no way to extract individual votes, so confidentiality is automatic.
Later: Notice that the ratio needs to be compared with the sex ratio of all users, which can be derived from the "About our users" poll. Taking into account the very low turnout, the ratios are about the same. That is, there are more men than women here, and the men are almost all gay, the women almost all strait. Given the topic is a love story about two men, this is hardly surprising.
