I have a strangely specific and at the same time, wide range of preferences, depending on what I'm in the mood for. However, there are just some things I don't ever say "no" to, and there are some things I will not try.
My setting preferences is vast: I will do from the medieval times, to modern, to futuristic dystopians, post-apocalyptic, to even space explorations. That being said, I do prefer the medieval times (be it renaissance or settings where there's kingdoms, to even dukedoms and the likes) as a point of interest because personally, I feel more immersed in creating boundless worlds with their politics and their own problems. That, and it allows for more of my fetishes to be incorporated, when possible over many other times (except dytopias).
That being said, when it comes to sci-fi, as I am an engineer, I tend to overthink things, so I tend to have problems with that setting at times. However, I'm willing to give it a go provided there's enough base and logic behind some things! (I might question or challenge an idea, however. . .)
As far as my fetishes go, depending on how light or how dark you want, I have a huge spectrum of it. As long as I don't list it on the "Will not Roleplay the following 'Fetishes'," I'm definitely willing to try. However, there are some others I have unlisted (for the ones I want to do, or even the ones I find to be my favorites) for now. I might add them here eventually, but for now, this'll have to do. However, definitely, hit me up: I'll be more than happy to talk to you about it.
That being said, I do prefer things to be leaning towards the darker sides: I definitely like exploring the dark sides of a plot; the feeling of helplessness, the feeling of regret, all of it in a story makes me feel . . . alive and relatable. I also like rougher things be incorporated in the story: tortures, bondage, interrogation, prison-life, and many others in the cluster.
As a final note, I am notably someone who doesn't play the "only take or give" game. The story should shape what kind of condition it is; even someone highly sadistic and dominant can, at a given condition, feel that helplessness and the feeling of being on the short end of the stick. Willingness to explore it is a big plus in my book!
