Okay, I’ll try to be a little bit more honest here.
Of course, being human, we all have our interests in different things that we enjoy. And being human, we all have some kind of a sexual drive. So I would be lying if I said I hadn’t thought about it. I have doodled some things, but only personally for myself and usually delete them immediately. Also, to be honest, I think drawing porn in general might actually be really good practice! Weird, right? But think about it, it really makes you think of human (or whatever it is your are drawing) anatomy. It also makes you push the boundaries of proportions and dynamic positions. It’s kind of like taking an art class where the models come in. You really have to think about where muscles go, how to connect them, shading, lighting, and so on.
So do I completely hate it? No! Am I kind of interested? Of course. Am I comfortable around it? Not really, no. I think it’s just the way I was raised. Sex for me is a personal thing that you wish to share with someone you deeply care for. Someone you want to open yourself to and share a life with hopefully down the line. Someone you can trust with all of you.. heart and soul, body and mind.
Would I be disturbed if I saw Rin smut drawings? Slightly. But if it was intimate and not spread around the internet a lot? Eh.. maybe I might be a little interested. Rin was based around myself, obviously. She would have a dedicated relationship to someone and wouldn’t be rag-tagging around showing herself off. That’s not who I am, or who she is.
So… have a heart. If for some reason you desperately want to draw something like that… be kind to my Rin and respect my character? Maybe talk to me about it first? I dunno. I’m not sure if I’d be more disturbed by it or try to commend you for trying. It’s a tough subject for me, being an artist and also being human and my personal opinions/feels about subjects.
