I prefer a lot of detail, also. I love drama, excitement, give and take between characters. I like my character to have a voice and if she's going to be forced I like her to be able to resist. Look at it as foreplay. In a consensual romantic scene posts that describe the setting, the characters and their feelings, give detail about what they're doing only add to the story and the ultimate act of pleasure. In a non-con story the same can be said for describing how the characters meet, their motivation, the feelings of anger, hatred, humiliation, fright, fear, terror, etc. I also believe that in a non-con story all the details leading up to the final taking of my character are important as well as all the details of the act itself.
When I read a story (and I do read many stories on the various forums) that has the act performed nearly right away and turns a strong and determined character into a whimpering, sniveling submissive, my interest is derailed almost immediately.
A story that is sex, sex, sex from post 10 throughout the story isn't necessarily a bad thing as long as it's set up that way to start and can be enjoyable if there is at least a little detail, interaction between the characters and descriptions of setting, feelings, clothing, behavior, etc.
I'd rather do no role play at all than do one that doesn't have a story (plot) and equal footing for the characters at least at the beginning, and the ability for the character to still be a force to be reckoned with throughout the story.
On a side note, I've been complimented several times on my descriptive abilities so if you write with me and don't let me express myself you may be missing out on a good thing.
