AHH ANOTHER PERSON? SURE I CAN TRY? It's difficult to give general writing tips, since everyone needs different advice for different things and I don't want to generalize. Also there's some things I struggle with and haven't figured out yet so... 😅 I can share how I conceptualize my own works, at least!

I view art as a way to communicate emotion. You can explain that you are sad, but you cannot have someone feel your sadness through just explaining it. So, if art is communication, writing is a conversation. I usually pick a topic/theme and then have that theme explored through a variety of character's perspectives. Instead of character "traits," I think of characters having "values," and these values will get tested as a way to explore this theme.

I'll give an example!

In my work But to you, it's just words... (aka Walking Sim), the main "idea" is about "forbidden knowledge," or rather "is it worth it to know something if it hurts you to know it?" Satoru's values say, "yes! It's absolutely worth it, in every circumstance!" Or rather, no matter how much something hurts to know, the acquisition of knowledge is always the most important to him. If a character values family over their own personal self, they might be a sacrificial type, etc. things like that, that's how I conceptualize characters. Obviously, not all characters will follow their values in every circumstance, and it's those circumstances that are the most interesting to read! (i.e. that's your character development :D) In a later section of Walking Sim, there's going to be challenge where he has to prioritize something above knowledge, but you'll have to wait until I get there LMAO

This absolutely works for porn, too. In my recent fic, Devil's Trumpet, I wanted to explore the idea of how the sober mind can be equally as "intoxicated" as someone under the influence, so Satoru's actions of impulsivity are a reflection of that irrationality. You can explore things like pleasure through pain, how loving someone can make sex feel better, shame, a particular kink!! there's so many options but it definitely applies to porn too!!!

I think something I need to work on is getting these thoughts down before I begin a story. I think often, I don't quite know what I want to say with a character, and they end up wandering around a bit (i.e. inconsistent), a good example of this would be Yuuji in Walking Sim. I think if I rewrote it, I would give him a lot more agency as a protagonist, and really challenge his values.

Aside from this, I really prioritize succinctness, or cutting things to be as straightforward as possible, but this also gives me the bad habit of stating things TOO bluntly, so subtlety is something I've really been working on the past couple fics. I know this isn't how everyone writes (and that's a very good thing lol) but I hope this helps!
