I removed the weird SF and horror tinges I was playing with in early drafts as the tone didn't match up to the competition's requirements - it's meant to be comedic erotica, but every time I sit down with the usual bag of tricks there seems to be an automatic slide towards more disturbing undercurrents. By removing the crutches of familiar storytelling elements it got a lot lighter (for some reason I can't get rid of Clive Barker's "sex and violence are two sides of the same coin" thing out of my head when I play in the erotica genre.
One thing that often doesn't work. When things are told in recall, you might not want to put them in the form of a dialogue, with paragraph after paragraph of quotation marks.
Um... Yeah. I'm going to have to do massive edits anyway, so I'll remove all the tags when I do so. It's
entirely told as if to another character.
So, why worry about making it 1st past if that feels wrong to you? (Again, I don't see why it would if it doesn't for other genres.) Write it in 3rd. Or present tense and see what happens.
There's an upper word count I have to stay under.

By limiting it to recollections, I removed about five thousand words of set-up, and got to the actual beginning of the story a lot quicker - it's still massively overwritten, but there is less weirdness I have to make note of for further edits...
This is why I should keep away from competitions I have no business entering. Or at least have something finished before I get the brainwave of entering...
