My books are in the Erotica-BDSM genre. I read an article recently about how people with BDSM sexual fantasies have been scientifically proven to have higher IQ's.
My books contain intensely dark erotica for the reader who accepts their kink. The person who identifies as more "vanilla" in their sexuality is often unconsciously acting out these energies in a codependent relationship, where they live a life of bondage. The person who can accept that these powerful forces are swirling around inside them is guaranteed less bound up.
I've written a few series in which the characters progress and evolve in their sexuality through the no holds barred exploration of it.
