It's a free library! Everyone will do as they please!

But CS, there are many of us - probably mainly authors who feel a bit sensitive about the competitive element of the Challenge, and want fairness - who do as Janine and others have said, namely, read and vote on all the stories and do so without orientation (or turn-on factor) being a criterion in our judgement. So, please do not be downcast - you KNOW, by the comments you receive weekly, how appreciated you are.
The contest inevitably involves some luck in terms of how many voting readers get to one's story, and we know that
Daddy's Naughty Knicker-Girl's Buns Bounce Red will be more appealing than
EU Agriculture Tariff Increase Tale . It's possible, too, that F/M readers aren't generally as ready to vote as M/F or F/F readers are (they're too sore, maybe! Having too much fun!) - who knows?
Alef expressed my own approach perfectly - after 21 months immersed in spanking stories, I'm almost immune now to their titillation-potential, and, in a contest, I look for what's well-crafted and original, whoever's bottom might be turning a redder shade of pale.
I've read them all now, and I cast 326 votes (an average of 5.8 a story). Of the 19,000 votes now cast, my guess is that about 45 of us voted on everything at a roughly similar rate, and the remaining 25% approx. of votes came from 'occasionals' of varying degrees, some voting on more than half, others on just a handful. Half the fun is in poring over the stats!
