I have read romances for as long as I can remember. Jane Eyre was my first and in spite of all my mature, feminist tendencies I have never really gotten over Rochester...
I them moved through every Georgette Heyer the St. Mary's library had. Brooding, dark men with dark pasts and even darker houses... It was more than this middle-class private-school girl could handle!
I then moved from covert attraction and simmering looks to Mills&Boon, which, when I was reading them, were filled with virgins, playboys, throbbing manhoods and undulating waves of ecstasy.
Then I got married and the joy of those books was lost to me forever. There's nothing like a real love relationship to totally destroy your ability to suspend disbelief about a housekeeper and her playboy-boss, or a nurse and her introverted-but-genius-widowed-surgeon-with-great-hands. I was sad. It felt like I had grown apart from a childhood friend. But just that that old friend, I knew there was no going back.
Then, thanks to my sister, I discovered supernatural erotica - or what we call 'vampire porn'. And its wonderful.
In the realm of the supernatural literally anything is possible. Succubi have shape-shifting tendencies, angels smoke Marlboro and demons appear as John Cusack. Once again its easy for me to suspend my disbelief and fall completely into the ludicrous delightfulness of it all.
Just Imagine the possibilities. Seriously. Imagine them!
Vampires are super strong, so some superhuman positions can be achieved in the barns of deserted farms at full moon... Nephilim can turn invisible - which makes for endless threesome fun, while magic powers mean erotic dreams can actually be physically experienced by both parties. (WOW!)
The situations that characters can get themselves into are endless. Cool, no? Supernatural sex is literally supernatural :-)
