[BookCat]

At the time of posting, you were only two thirds through your first draft ... you are nowhere near publication. Firstly, finish the first draft, then put it away for a couple of weeks. Next, load it into your chosen reading device (or print it out if you don't have one), sit back, cuppa in hand, notebook beside you and read it as though you hadn't written it yourself.

Make occasional notes concerning plot holes, or events in the wrong order, or maybe other things which would be better altered. Then, when you've finished, ask yourself if you would really pay good money for the book you've just read.

Go back to your computer, make the necessary structure alterations and fill in plot holes (get the times that events happen consistent). Then do a detailed textual edit.
The textual edit involves changing the syntax, word choices, grammar etc.

When you're finally happy with it, get some beta readers who are okay about reading erotica to read it (avoid friends and family, they'll just say it's great). Using their feedback, make more alterations if you wish.
Or send it to a professional editor (personally, I'd do my own editing, but I can be ruthless with my own stuff).

Then consider publication and all that entails.

Don't let this put you off, the editing can be great fun it's the getting the words on the page initially which is tough.
