Some of this is inspired by real life but a lot of it is just created for the setting. I put a note next to one item in particular that gave a pre-reader a concern as to whether that was actually a thing that happened in real life. Also note that I am cis myself, so I have limited perspective on some of this stuff. I have help from people that know more than me and they've generally approved of this write up. If I can get a good write up for 2nd mechanics done I plan to include something like this in the book.
The General Public
The average human considers sex to be an intensely personal and intimate subject not to be discussed in open conversation. Many major religions include a concept that sex is at best a distraction from greater issues and at worst a dangerous lure to sinful behavior. Individuals that espouse a philosophy of being more open about sex and the discussion of it are often characterized as making excuses for promiscuous behavior. This is to the point that most cultures avoid giving their adolescents anything like a proper education on how sex and sexuality works. In this culture of avoidance and willful ignorance, deviations from the norm stand out and tend to make people feel uncomfortable.
