One does have to wonder what motivation exists behind the people who constructed this forum to pose such a question. Nonetheless, it does have its provocative elements.

To answer in short, Word Pictures. Many of which are posted to the bdsm library pages.

Before the shout Shameless Self-promotion! is raised, keep in mind that word pictures provide a mainly constructive way to avoid being the next poster person for psycho desk references.

And one source for inspiration in this corner comes from a stauesque blonde bombshell. Anyone who has ever set foot in a gambling casino can appreciate the turned heads and distracted eyes of the pit bosses as this person walked past their tables.

Is that a definition of "Beauty", or what?

Plus, this ravishing looker also was extremely kinky.

So one way of expressing one's Sexual Fantasy can be through words. Are they as satisfying as the real deal? Any comparison is like comparing apples to oranges.
Now, is it just me or does that lack sense? I'm really confused!
