I write erotic short stories myself, and I have had experience editing and beta-reading fan fiction of all varieties.
There isn't much that I won't read, but I wasn't keen on M-Preg in the fan fiction genre. It just stretched things a little too far, if you know what I mean.
I have also had experience editing and writing historical romantic fiction, specialising in accuracy in time,place and language. Just because it's erotica, doesn't mean we have to be historically inaccurate.
Happy to have a look at anything, and I'll be honest with authors and let them know ASAP if I can't work with their theme.
Bit of a grammar and spelling freak, but not too bad. Love working on plot and character development, and was a fiend on keeping things canon in fanfic.
And as you may have noticed, I use British English spelling. So my editing programs will change your spelling from US to British or Australian. I might forget to change it back for you, but don't hold that against me.
