Smut lessons.

Okay, heres the thing guys, I love slash, the entire genre facinates me, and Im sure you know what I mean by that.
But the thing of it is..................Im a fluff writer.
I specialize in the Fluffiness and romance of two men but I am however lacking in the erotica and raunchyness that seems to be such a hit.
I love reading raunchy and erotic slash (excluding Freard, dont ask me why, it just annoys me and its to repetitive, I cant enjoy it) (To each there own people) So you would think, with the level of smut i read, that I would be expirienced........well, not so much.

Ive been told Im a pretty good writer, I just need some suggestions, Im basically asking the question "What is kinky in slash?".

So, what is kinky in slash? Any suggestions?
