Writing and orientation.

A couple of things. First, I don't think this kind of story is going to be much fun to reader or writer if it doesn't excite the writer as (s)he writes it. F/M and M/M just leave me cold. Nothing against these oprions, but they can't excite me so what I wrote about them would almost certainly be unconvincing (I did have Geoffrey Parslow spanked by a revengeful Sunita Sharma, on the way to the tables being turned, and that was an exploration of GP's humiliation, but I did NOT find it sexy!). We're not being paid for writing these stories, so it makes sense to write what you like.

Secondly, I am fascinated by the cultural geography of sexy spanking, and would love to hear more from people outside the UK, USA, Canada and Australia about how the scene differs with them. It seems widespread in Europe and the "white colonies", and certainly touches a spot in India and perhaps Latin America, but apparently not much in formerly colonial Africa except South Africa. However, there does seem to be interest in Japan, which was never colonised unles you count the US occupation.

There was somebody from Nigeria who posted on another spanking forum I used to visit. He was kind of a creep, but his existence proves that our fetish exists in other sub-Saharan countries besides South Africa.

Getting back to the topic of the thread, I pretty much agree with barretthunter. I'm turned on by F/F, M/F, and F/M, so that's what I write. I might try to do M/M someday just to make the yaoi fangirls happy, but it would do nothing for me, and I'd have little personal motivation to finish it.

Within a single story, I'm only M/F so far. But with a series I try to expand to F/F, F/M, and even m/F.

My experience is almost entirely M/F but I've written F/M and my most popular stories are F/F.

I've written mostly M/F, with smaller but significant numbers of M/f, F/F and F/f, and only a handful of F/m. Nothing F/M as yet. I write what interests me, which covers a lot more than just orientation.

I'm pretty much an equal opportunity guy. Celebrate diversity! I write M/F, F/F and F/M in all their variations. I just don't do M/M (not that there's anything wrong with that).

As Barrethunter said, most if not all of us write for our personal satisfaction and the hope that we amuse and titillate our readers.
It therefore follows that unless we are writing to a pre-determined formula, we will write what interests or gives us pleasure.
Contests are an amusing challenge, which make us write to the subject.
One thing that I used to enjoy enormously were the chain stories on Alex's Flaming Cheeks; what was fun was that you would leave the story in a certain way and the next few authors would completely change the way it was going, often with very funny results.
To make it work you need about 6 to 10 writers and a starting theme!

Indeed, it is fun to pick up someone else's story, and those Flaming Cheeks chain stories often took wild changes of direction as each author forced the story line back to their own interests.

Back on topic, BH is right, unless we enjoy writing it what hope is there that it will interest a reader? Personally I've written all genres including ?/?. This is because I'm more interested in what's going on in between the ears of the protagonists than anything else. I don't think I've done m/m because I don't find it interesting.

Having said that, what I like to read is a different thing entirely.
