Goodness, my mind went straight to BDSM too!
Okay...back in the summer of 2012, when I was a wide-eyed aspiring writer who didn't know AW existed, I did something weird. I had 3 manuscripts (2 novels, 1 novella), that no one had seen except for my significant other (*ahem* do not follow in my footsteps, whatever you do...) I had no idea if my writing was good or not, and I didn't stumble upon the concept of critique partners and beta readers until much later.
So I randomly (based on, well, Google), decided upon 3 dream publishers--Ellora's Cave, Harlequin, and Entangled. I sent 1 MS to each. Needless to say, I got rejections from all three.
The first was from EC--form rejection, and they even spelled my name wrong.
Harlequin's form reject came in not long after. Again, form...and it included a lengthy "general writing advice" section. At least my name was correct.
Entangled's came last, and it seemed like a personal/form combo to my untrained eyes (though it could have as easily been a very well-written form reject).
There you go--3 first submission experiences for the price of one
[Side Note: Though I trunked the first two novels (yes, after they netted 1 rejection each, bringing their total viewership to 3 people), the novella Entangled rejected was eventually picked up by Liquid Silver--this is after I stumbled upon AW and discovered (a) I could send an MS to more than one publisher, (b) a wide range of small press erotic romance publishers existed, and (c) if there's bondage, I really need to put "BDSM" in the intro email, and perhaps not send it to Harlequin. Lesson? A little research goes a long way, but since you're already on AW, you're waaay ahead of where I was
