It doesn't really matter how organized or flashy your request thread is. What matters is the content, and more specifically, what you are advertising. Sadly, most people use this website as source of smut. They aren't necessarily looking for good stories, well thought-out plots, or even decent character development. They just want to write smut so they can get off, or use it to quell their sexual frustration. There isn't anything inherently wrong with that, but it can be discouraging to those that are seeking more. If you're following the popular trends, and list the right kinks, you'll be awash in partners (theoretically).
Your thread is fairly concise, and very easy to breeze through. Outside of cosmetic changes, something I'm not great with, I can't think of any particular changes you could make. Your thread is the type of thread I prefer to read though. If I see blocks of text under a header that is neither: plots, story, or writing samples; I will typically ignore it entirely, or close the tab. I don't care to read through someone's elaborate preferences, or lengthy self-introduction. A short list of rules or preferences is what I like to see.
It also helps if you're perceived as being a woman, who is looking to be as slutty as possible. I believe the majority of the people on this website are male (not that there's any good way to track this). Generally, male role-players have a smaller pool of people to role-play with. Those advertising as female have many male applicants, and are usually more open to playing with another female. That "gay" stigma isn't there for them (to such a degree). Male culture is full of men who prefer to distance themselves sexually from other men, regardless of the circumstances. They don't want to feel gay by role-playing against another man, or at the very least, they feel that it is a turn off if they're typing dirty shit to another stiff cock. Almost paradoxically, they don't mind watching a guy jerk off until he cums on a woman's face, go figure. So, the pool of potential partners for men is smaller than it is for women (or at least the people writing under either gender).
Anyway I'm kind of ranting at this point. Personally, I like your thread. However, I don't much like role-playing these days. You just have to be patient and stick to your guns.
