And then thought of Heinliens character "Lazerus Long"
From wiki
The promotional copy on the back of Time Enough for Love, the second book featuring Lazarus Long, states that Lazarus was "so in love with time that he became his own ancestor," but this never happens explicitly in any of the published books, although one can speculate that the descendent(s) referred to by Heinlein were the identical twins Lapis Lazuli and Lorelei Lee that were cloned from Lazarus. In the book, Lazarus does travel back in time and is seduced by his mother; but this happens after his own birth. Heinlein did use a similar plot in the short story "—All You Zombies—", in which a character becomes both of his own parents.

I quit reading Heinlein's Sci-Fi when I was about 30, but he had a huge influence on my sexual mores because he crossed almost all sexual boundaries, (although he was a bit homophobic) not usually with ugliness, usually with what he saw as love and/or acceptance (for his time)
(CJ Cheeryh and Octavia Butler both Sci-Fi writerswho addressed sexual mores, by human mating/sex with a literal 'other' an alien being, and what that might look like)
And then, having been exposed to a number of ideas, relationships and results of behaviors from a variety of sources, I adopted 'do as little harm as possible' as my personal code. Being female and self identified feminist, I began to look for these places of harm, both within and without, not just harm I had sustained, but harm I had caused. Harm that might be institutionalized. Harm done blithely, without a thought to consequences, because that's 'just the way it is' What I thought the nature of that harm was and why. What I identify as harmful drives my activism.
It's something I thought deeply about and think about often still, because its subjective. I think porn as it is now is almost always, but not always, harmful for the same reason I think prostitution is harmful not because there is anything inherently wrong with it, but because it is unequal and degraded. If solace could be found in the arms of a trained sex professional or either gender whether one was male or female, in clean and safe and respectful surroundings my opinion might change. If pornagraphy most often transmitted joy and sensuality as well as open eroticism instead of hurt, racism, sexism and unasked for domination I might change my mind.
Ironically The SMBD club I'm familiar with (no not as a participant) is very careful with its members; there is an entry interview for members education so there are clear understandings of safe sex and safe words. The members are often working out psychological demons, and just as often move on. That's a world where the potential for harm is great, and those involved know it. It's not that harm doesn't happen, but great physical harm--while always a possibility-- isn't as much of an issue as the psychological harm in that atmosphere.
Kant was a hell of a thinker. I have my Mother's Copy of "Critique of Pure Reason" I hope to pass it down to my grandchildren.
