Thanks for all the recommendations, I'll definitely look out for Frank and I. I'm looking for BDSM fiction mainly as opposed to just "spanking", then again "spanking" can mean different things to different people, to me it means just that, mainly hand spanking and not use of implements (I like implements, LOL, lots of them). I did mention a few things in my initial post but basically I like all the initials, LOL, mainly M/f with a little F/f for variety and I am more interested in the "play" than I am in reading long (and often badly written) sex scenes with horrendous terms such as "love juice" and "rampant rod", LOL, I can't keep a straight face when I read stuff like that which kind of defeats the object of reading erotica in the first place.
I just read the first two books I wrote, Dominant by Felix Bishop (didn't realise it was written by a man or I probably wouldn't have bought it), not my cup of tea, let's just say it was obvious a man had written it and regardless of the icons on the cover it was mainly about domination, there were S/M in there but there was too much sapphic stuff in there for my taste (naturally with Cole involved all the way, every man's fantasy, yawn) which was not apparent from the description, I don't mind F/f BDSM but this seemed to be more an excuse for lurid sex scenes. Saying which, it did incorporate some useful information about safety, it was the story of Cole, a man who gradually indulges his desire for domination with a variety of women before finding "the one", it wasn't terrible but most of it didn't really sync with my personal tastes.
The second novel, Secrets of the Whipcord by Michaella Wallace, was better, but the backstory was not all that well written, it involves a so-called frigid woman who has no interest in sex at all until she buys the book of the same name, looking at the pictures and descriptions of S&M scenes (M/f in the main) arouses her (the book is sort of magic), there really is a Society of the Whipcord and her flatmate is a member, the book is stolen and they are worried the society will use it to entrap innocent women into the society as opposed to those who come to them of their own free will. The heroine joins to try and get the book back and the story is largely of her 5 initiation ordeals and what happens to her friend when she tries to steal the book back. There were erotic scenes in there but a lot of the initiation stuff was crowd scenes where she was the only submissive there, not really my taste, I'd like something about a more intimate one-on-one relationship in the main. As I said, the story was thin and the ending frankly unbelievable, just because its porn/erotica doesn't mean it shouldn't be well-written, take the stories on this site as an excellent example, there are many good writers posting on here (frankly a lot of them are far better than the two novels I have read so far).
I'm not too disappointed though as I only paid around £5 for both of the books via Amazon Marketplace secondhand, a precaution I'm glad I bothered with

I'll report on the two Josephine Scott books once I've red
