I don't know about you guys, but I think it will be really interesting to explore how sex and sexuality would develop in the Madnessverse, especially societies acceptance of prostitution, pornography, erotic art and literature, and non-traditional genders and sexual identities. Is there a Sigmund Freud and a Carl Jung? Masters, Butler and Kinsey, will they exist? What about the development of scientific studies on sex, sex reassignment surgeries, the production of condoms, satisfiers, and contraceptive pills? I imagine, for instance, the Europans being very similar to OTL France during the Belle Époque and the roaring 20s: much more open-minded than it's neighbors. West Germania, Italy, Austria and the Southern German States before the advent of Peter I and the new HRE, will be similar, I guess. I'm not sure about the Illuminist ideas on sexuality, they can be either extremely liberal or extremely conservative -as most communist states were IOTL. Eduist Brazil and the Neutrality Pact Nations, I believe would be much like their OTL counterparts of the time: male promiscuity and brothel frequentation is tolerated and even expected, with female and LGBT sexuality frowned upon or repressed, and erotic art and pornography banned but circulating only underground. Now, it's in the RU and the other Fascist Nations with their racial ideologies that things get interesting: is Better-Infee intercourse considered bestiality? What about intercourse between different Better races? I can totally imagine underground literature, art and films depicting such acts being strictly forbidden but still circulating and widely popular.
