Look into joining a writer's group (though you may have problems if you are writing BDSM related stuff as there are none that I know of) or start one yourself. A writer's group gives mutual support to writers, advice and information. You can also get someone to proofread/line edit.crit anything you write.

I've had some experience of editing (not professionally in that I got paid for it in any way but a book currently in print was heavily edited by me... even got an acknowledgement for it ) so I would be willing to read through it for you and tidy up the grammar.

As for publishing, there are a lot of small publishing companies out there who may be interested in publishing it, Failing that there are also PoD (Print on Demand) publishers who allow you to print anything and will even help you market it. www.lulu.com is one that I know of. If you want any actual copies to sell yourself, you have to pay Lulu to print them but they will ship to Amazon and similar website customers on your behalf and pay you the profit once they have taken out their cut (which can be quite a lot).
