If you're not 100% male or female I will puke all over myself, kthxbi.
Woman with AIS queries Ask Metafilter about revealing this condition to potential sex partners.

A quick reply: I know we're all supposed to be PC about "intersex" conditions, but I think you're taking advantage of that expectation of sensitivity. Genetically, you're male. You don't just have a smaller vaginal canal; you have (or had until they were surgically removed) testes. Or in the vernacular, balls. In gaining their "consent" under false pretences, what you're doing is little different than getting someone to have sex by getting her drunk or slipping her a ruffie (sic).

Things go to MetaTalk and then get a little bit absolutely batshit fucking crazy. From XY = genetically male MUST INFORM YOU HAVE BALLS, non-science type plebes to actual science on why that's bullshit to not disclosing your entire medical history is one thing, but having sex with a heterosexual male without disclosing that you once had testicles that were surgically removed is entirely another. BEING STRAIGHT ISN'T PREJUDICE, you asshole to more Godwin and race references than you can shake a stick at, we have hundreds and hundreds and hundreds of comments that are, as always, best summed up by quonsar: oooo, the tightness! what's her phone number?

There may be more but I couldn't finish the MeTa thread. The rage this gave me, it was too much.
