- What are the rules for Kinjiki (forbidden colours)? Which colours are restricted to what rank?
- What do the shogun's heir do before inheriting the title? I know usually daimyo's heirs would become commanders of the army, but the shogun?
- Considering the homosexual practices, are there lubrication? Do men have anal sex with women?
- I read somewhere that in this period it is taboo to do cunnilingus/fellatio. Is this true? I cannot for the life of me remember where I found it but it was a blog, so it's a dubious claim at best.
Searched "history of sex practice in Japan", "kinjiku colours in clothes", "court wear colours". Not finding anything good so far.
